This post focuses only on the results of the testing in the $500+/month price bracket for WordPress Hosting.

Enterprise WordPress Hosting Introduction

This is super exciting for me to test the ultra high end of the market. The past three years I've focused entirely on entry level plans, but the market has changed tremendously since I started and there is a very real demand for Enterprise WordPress hosting. I think this is the first time that a lot of these companies have been benchmarked, especially at this scale and level. So I hope this adds a new and incredibly valuable door for the minority of sites out there that really need to handle massive amounts of users.

The Enterprise testing this year had some fundamental differences from all the other testing that need to be discussed upfront. These are huge and expensive systems that are normally customized on a per-customer basis by these companies. They all offer a much more hands on experience than hosting plans at the other end of the spectrum and charge accordingly. For that reason, I felt it was only responsible to change how they were tested slightly.

The first change is there is no default setup, which is what I test in every other price tier. The companies were given explicit permission to customize their platform and knew what tests were coming their way. Some even ran their own load tests to make sure they were going to perform as advertised and made changes. This is what I would expect from plans charging hundreds, if not thousands of dollars per month for large sites. So I wanted to let them perform their normal services for this tier.

Uptime monitoring was reduced for many companies in this tier. Since these plans are very expensive and consume huge amounts of resources, I didn't want to keep my test sites eating up lots of money and resources. If they had other plans entered into the system, I created a composite based on what all their other plans averaged for uptime.

Discussion of Load Storm Test Results

First off, this is the biggest load tests I've run to date. I had limited resources and wanted to test a high enough number to really put some stress on these systems. 10,000 concurrent users seemed like a reasonable choice based on limited resources and high enough to be meaningful for sites that are truly getting a lot of traffic.

Kinsta and Pagely [Reviews] had basically flawless performances. Flat average response times, minimal errors and no spikes.

WordPress.com VIP had a nearly perfect looking run except for some minor issue with wp-login that might be security related but persisted the entire test at a tiny level (0.17%). The average response time was impressively flat and the fastest of any company by a good bit at 101ms. They also maintained the lowest peak response time. WP VIP also loaded a lot of extra scripts that nobody else did, which increased their transfer data to be multiple times higher than anyone else.

Pantheon [Reviews], Pressable and Pressidium each had minor spikes but put on nearly perfect performances otherwise.

WPEngine [Reviews] ran into what looks to be a similar issue to the other tests, wp-login/admin security issues. Which caused a lot of errors and makes the test look not great. However, their average response time was flat, but it's really hard to say with such a high error rate (16.37%).


2. Blitz.io

Test 1-5000 Concurrent Users over 60 seconds

Discussion of Blitz Test 1 Results

This test is just testing whether the company is caching the front page and how well whatever caching system they have setup is performing (generally this hits something like Varnish or Nginx).

Who performed without any major issues?

Kinsta, Pagely [Reviews], PantheonPressablePressidium and WordPress.com VIP all handled 5000 concurrent hits to the frontpage without any issue. The largest spread in response times among all of them was a minuscule 20ms. Pagely even managed an impressive perfect no errors or timeouts.

Who had some major issues?

WPEngine [Reviews] struggled with this test. Around 20 seconds into the test, there was a substantial increase in response time which continued to slowly increase for the rest of the test. The errors and timeouts started to kick in 5 seconds later at the 25 second mark and also gradually increased until the test ended.

3. Uptime Monitoring

Both uptime monitoring solutions were third party providers that offer free services. UptimeRobot was paid for and monitoring on a 1 minute interval. All the companies were monitored over approximately two months (May-June 2016).

For Enterprise testing, many of the plans were only setup for a short period of time because of the enormous cost involved with setting these up. Only WordPress.com VIP and WPEngine were monitored directly. The rest are composite scores based on the other plans companies entered in and the company's average uptime as denoted with an asterisk (*).

WordPress.com VIP 100 100
WPEngine 100 100

* Composite uptime based on all the plans entered in 2016 testing from a company.

Every company in the enterprise tier seems capable of keeping their servers online, thankfully.

4. WebPageTest.org

Every test was run with the settings: Chrome Browser, 9 Runs, native connection (no traffic shaping), first view only.

Company WPT Dulles WPT Denver WPT LA WPT London WPT Frankfurt WPT South Africa
Kinsta 0.718 0.588 0.958 1.256 1.741 5.844

WPEngine 2.255 22.971 2.115 1.722 1.846

It's not surprising that these companies deliver content pretty quick all around the world. What is interesting is WordPress.com VIP was the fastest to Sydney, Japan, Singapore, South Africa, and LA. Kinsta was the fastest in Dulles and Shanghai. Pantheon was fastest in Denver. WPEngine was the fastest to London. Pressidium was the fastest to Brazil. I'm not sure how meaningful it is, but it's interesting to see the most expensive product having the fastest load times in locations all across the world.

5. WPPerformanceTester

Company PHP Bench [Seconds] (lower=faster) WP Bench [Queries Per Second](higher=faster)
Kinsta 11.37 320.82
Pagely 9.136 249.81
Pantheon 11.322 216.31
Pressable 10.834 491.64
Pressidium 10.958 367.24
WordPress.com VIP 2.244 500.25
WPEngine 13.178 533.9

I'm not sure what WordPress.com VIP is running, but it put up the absolute fastest scores in the PHP bench that I've seen by a wide margin. Roughly triple the speed of the next fastest which had a 6.5 second score. Every other company looked to be in the normal range between 9-13 seconds.

Another interesting part of the results here is that nobody was really going much faster than 500 queries per second in the WP Bench. I don't think a single one is running a local database which put up some blazing fast speeds in the lower tiers. If you're looking to host enterprise WordPress sites, you lose that no network latency performance, but certainly gain in reliability and scalibility.


White glove service and hefty price tags makes for some spectacular performance. It's nice to see that if you really have a site getting millions of visitors per day, there are a lot of really solid choices out there who can handle the mega WordPress sites that need Enterprise level hosting.

Top Tier WordPress Hosting Performance


Kinsta, Pagely [Reviews], PantheonPressablePressidium and WordPress.com VIP all offer Top Tier Enterprise WordPress Hosting. None of them had any real struggles with keeping their servers up, the 10,000 and 5,000 user load tests. If you can afford them, they all seem worthy and capable.

Individual Host Analysis


Kinsta had essentially perfect LoadStorm and Blitz tests. They also had no flaws in any other tests. I'm at a loss for words to praise their performance.

Pagely [Reviews]

Pagely aced it. The fewest errors on LoadStorm and a no errors on Blitz. I can't find any faults with Pagely's Enterprise offering.

Pantheon [Reviews]

Pantheon really stepped it up for the Enterprise testing. Effortlessly went through the Blitz test. They had a some minor spikes in the LoadStorm test and their average response time started to creep upwards but nothing worth being concerned over. Overall, a top tier performance.


Pressable performed nearly identical to Pantheon. Excellent Blitz test, some minor spikes and increase in response times in the LoadStorm test. The uptime was the lowest of everyone with UptimeRobot having an average of 99.90% which has been my border for pass/fail. I gave them top tier, but they were about as close as you can get to the edge.


Pressidium had a nearly perfect Blitz test with 2 timeouts and did excellent on the LoadStorm test which had 2 very minor spikes but maintained a nearly flat average response time otherwise. Easily a top tier performance.

WordPress.com VIP 

WordPress.com VIP was by far the most expensive plan tested and it put on a fantastic performance. It had a near perfect Blitz test. Despite having what appeared to be a security issue on the LoadStorm test it had the fastest average response time at 101ms and moved more data than any other company by a wide margin because of the custom scripts. But that didn't seem to negatively impact their performance at all. I'm also not sure what sort of hardware they are running by they blew my WPPerformanceTester PHP bench out of the water. Despite the highest price tag, they put on an amazing show and easily earned Top Tier Enterprise WordPress Hosting status.

WPEngine [Reviews]

Unfortunately, WPEngine was the only company in this tier not to do well in this tier. They struggled in both load tests. LoadStorm looked like it may have been security related, but Blitz looked like it really had trouble with the load. I believe the plan I tested cost $600/month, but the sales team wasn't willing to give me specific pricing for their enterprise tier.

Discussion of Load Storm Test Results

Kinsta and Pressidium were clearly the two best performers in this test.

Pressable had some minor issues that looked like they may have been security related to wp-login.

MediaTemple [Reviews] had a spike of errors at the very end and some minor errors throughout the test that might have been security related since they didn't impact response times at all.

PressLabs had some spikes and wp-login related problems but the server started to slow down its response times as the test progressed.

Pantheon [Reviews] had similar issues to PressLabs with slowing down and the largest chunk being wp-login related.

SiteGround [Reviews] started to have trouble around 12 minutes in and saw spikes, also mostly related to wp-login/admin. They also had increased and unstable response times associated with the spikes.

Pagely [Reviews] struggled the most with this test with spikes and increased response times. wp-login again was the worst offender.

What is amazing is none of these companies completely failed with 5000 real users logging in and bursting caches.

Who performed without any major issues?

Kinsta, Pantheon, Pressable, Pressidium, PressLabs, and SiteGround [Reviews] all had close to no errors (and exactly none in PressLabs's case).

Who had some minor issues?

Pagely [Reviews] had a couple spikes which increased response times and errors.

Who had some major issues?

MediaTemple [Reviews] had an early spike and a big spike later. The big spike later looks like it may have partially been a security measure. But it did eventually increase response times as well.

3. Uptime Monitoring

Both uptime monitoring solutions were third party providers that offer free services. UptimeRobot was paid for and monitoring on a 1 minute interval. All the companies were monitored over approximately two months (May-June 2016).

Pressidium 99.95 99.99
PressLabs 99.99 99.98
SiteGround 100 99.99

I hate having to penalize a company for uptime, but Pressable recorded 99.88 and 99.90 uptime scores which is below the 99.9% I expect from every company.

Every other company did well.

SiteGround 2.496 22.431 2.051 3.27 2.034

Fast. Not much to really say about these results. Nobody had issues, nothing was particularly interesting here other than nobody can get into China at any price level.

5. WPPerformanceTester

Pressidium 11.902 304.79
PressLabs 8.055 841.04
SiteGround 17.082 738

Not sure why SiteGround's PHP bench was so slow. The average WP Bench scores are also lower than every previous tier with PressLabs leading the way at 841. These more expensive solutions are generally trending towards cloud/clustered solutions which have slower database throughput in exchange for scale.


The high end WordPress hosting market is growing and has a lot of good options. No company in this tier completely faltered during the load tests despite a huge strain being put on them  of 3000 concurrent hits to the frontpage and 5000 logged in users browsing the site.

Top Tier WordPress Hosting Performance


Kinsta and Pressidium clearly led the pack in terms of performance. They were the only two companies that handled LoadStorm without issue. They also didn't have any other issues across the other tests.

Honorable Mentions

PressLabs earned itself an honorable mention. It had some issues with the LoadStorm test but it managed to stay up and did well on all the other tests.

Individual Host Analysis


Overall, a splendid performance that earned them top tier WordPress hosting in the $201-500/month range. No faults in their performance at any point.

MediaTemple [Reviews]

It's nice to see Media Temple playing with the big boys and doing a respectable job. They had a little bit of trouble with the LoadStorm test and some possibly security related issues during the Blitz test which kept them out. But they weren't out of place in this bracket and were by far the cheapest at $240/month.

Pagely [Reviews]

Pagely had some minor problems with the Blitz test but the LoadStorm test really seemed to be the big problem. The 5000 users seemed to clearly tax the server too much. Pagely reviewed the results and issued a full explanation. Their tl;dr was "Wrong plan/instance size for this test.
We price the value of our human Support and DevOps resources into the plan cost, which puts the ideal Pagely plan for this test outside the $500 cap. If the customer does not utilize the full range of services we provide they are essentially overpaying for AWS instances that in this case were undersized and not tuned for the test. "

Pantheon  [Reviews]

Pantheon did well everywhere but LoadStorm which was a common theme for this bracket. They didn't fail, but they certainly were being taxed with increased load times and error rates.


Pressable could have earned an honorable mention if it wasn't for some uptime issues. They found themselves just below my 99.% expectation. They handled Blitz without issue and LoadStorm looked pretty good except wp-login had some what I imagine was security related issues.


I'm running out of positive adjectives to say how well Pressidium has done this year. A perfect LoadStorm test with zero errors, the lowest peak response time and lowest average response time. Followed up by a near perfect Blitz test. Top tier for sure.


PressLabs was the only company to earn an honorable mention. They had a bit of issues in the LoadStorm related to wp-login of course, but other than that put on an excellent performance.

SiteGround [Reviews]

In an odd twist of fate, I accidentally ran the same Blitz test on their lower priced cloud platform and it did better than the dedicated server. The shared infrastructure can often have far more powerful hardware backing it than dedicated machines and that's one of the interesting results. For large bursts, it may work better. Overall, this plan did pretty well, but LoadStorm clearly overloaded the server a bit too much to earn any special recognition.

Discussion of Load Storm Test Results

KinstaLightningBaseLiquidWeb [Reviews], Pressable, Pressidium and SiteGround [Reviews] all handled this test without any serious issues.

MediaTemple [Reviews] had some minor issues with spikes and increasing average response times.

Pagely [Reviews] had some spikes but more concerning was the increased response times which were averaging around 3000ms during the 10 minute peak of the test. It kept the website up and error rate low enough (0.5%), but it was definitely struggling to keep up.

BlueHost [Reviews], CloudWays [Reviews] (Amazon + Google) and Pantheon [Reviews] all struggled with this load test. BlueHost crashed (85% error rate). CloudWays Google had 48% errors. Amazon fared better with only 24%. Pantheon had the lowest error rate at 14% but all of them were unacceptably high along with increase response times.

Discussion of Blitz Test 1 Results

This test is just testing whether the company is caching the front page and how well whatever caching system they have setup is performing (generally this hits something like Varnish or Nginx).

I also mistakenly ran an extra thousand users against SiteGround (1-3000), but since they performed perfectly, I figured why not just leave it. The chance for random network timeouts is always there, they got a perfect score, I let them keep it. That's why their numbers look higher than everyone else's.

Who performed without any major issues?

KinstaLightningBaseLiquidWeb [Reviews], Pagely [Reviews], PantheonPressable, Pressidium and SiteGround [Reviews] all handled this test without any serious issues.

Who had some minor issues?

MediaTemple [Reviews] had some minor issues with load starting to impact response times and some errors/timeouts at the end of the test.

CloudWays (Amazon) managed to keep the server up but started to lag around 35 seconds in with some errors at the very end.

Who had some major issues?

BlueHost [Reviews] and CloudWays (Google) both failed this test.

3. Uptime Monitoring

Both uptime monitoring solutions were third party providers that offer free services. UptimeRobot was paid for and monitoring on a 1 minute interval. All the companies were monitored over approximately two months (May-June 2016).

LiquidWeb put up one of the fastest scores on the PHP Bench at 7.177. Everyone else fell into the 10-14 range we generally see.

The WP Bench saw some slow scores from MediaTemple and Pagely and handful breaking the 1000 barrier in LightningBase, LiquidWeb, and SiteGround. Interestingly, the trend seems to be slower as you go up in price as you get more non-local databases.


This is the last really crowded bracket as we go up in price. It's sitting right at the border of entry level plans and the more serious stuff. This is the first tier that tested plans more heavily than any plan last year as well. The results were also very encouraging.

Top Tier WordPress Hosting Performance


KinstaLightningBaseLiquidWeb [Reviews], Pressable, Pressidium and SiteGround [Reviews] all earned top tier WordPress Hosting for the $51-100/month tier.

Honorable Mentions

MediaTemple [Reviews] and Pagely [Reviews] earn honorable mentions. They had some minor issues in the LoadStorm test and MediaTemple had some minor issues in the Blitz test.

Individual Host Analysis

BlueHost [Reviews]

BlueHost fell short again in the load tests.

CloudWays [Reviews] (Amazon + Google)

CloudWays is always interesting because you can compare head to head performance on different cloud platforms. I would pretty confidently say that Amazon outperformed Google in this instance with similar specs (although Amazon charges more).


Kinsta's entry level plan put on a fantastic performance. The higher end providers are starting to show up in this price tier and really showing why they charge their premium prices. Kinsta easily earned top tier status.


LightningBase's most expensive plan that we tested this year (although they offer higher ones), and for the third consecutive price tier (and year), they handled the tests flawlessly. A literaly perfect score for LightningBase: 100% uptime on both monitors and 0 errors on all load tests. Simply perfection. Undoubtedly a top tier WordPress Host.

LiquidWeb [Reviews]

LiquidWeb is a newcomer to this testing and this is their entry level plan. Boy did they make a positive splash. 100% uptime across the board and excellent load testing scores. They also had the fastest PHP Bench in this bracket (and third fastest of any company this year). They have a fantastic reputation here at Review Signal on our reviews section, I can confidently say they also have a top tier WordPress Hosting product to boot.

MediaTemple [Reviews]

Media Temple earned an honorable mention which is a step in the right direction. They had some minor problems with the load tests. No major concerns, just need to figure out security issues and minor performance stuff to make them top tier again.

Pagely [Reviews]

Pagely was a bit of a disappointment. They've been in the top tier the past years but fell to an honorable mention this year. The increased LoadStorm test seemed to put some strain on the server and caused spikes and increased load times. Everything else looked very good like previous years.

Pantheon [Reviews]

Pantheon, like Pagely, struggled with the LoadStorm test, but to a larger degree this year. It knocked them out of the top tier and didn't even earn an honorable mention in this price bracket. Everything else looked very good.


Pressable showed up in a big way. No problems in any of the tests. Zero errors on both load tests. Easily in the top tier for this price bracket.


One error, nearly perfect uptime. Hard to really expect a better performance. Pressidium's entry level plan remains in the top tier for another year.

SiteGround [Reviews]

I screwed up with the Blitz load test and they got a perfect score with an extra thousand users which is impressive. They had a small spike at the start of the LoadStorm test but otherwise put on a flawless performance with 100% uptime on both monitors as well. SiteGround is in the top tier.

There is a notes section at the bottom that details the minutiae of changes made to plans at the end of this post. Nearly every single company had security issues that I had to get around, so they worked to make sure my testing went through properly. Load testing often looks like an attack and it's the only way I can do these tests.

The Products

This year is a bit different than years past where every company and plan competed against one another. When I started the price gap was from $5/month to $29/month. Last year the gap was $5.95 to $299. I was only testing entry level plans but the market has dramatically changed since I first got started. Today, there is demand at many different price points and lots of companies have gone upscale with WordPress.com VIP at the top of the price bracket starting at $5,000/month. The only logical way to break things up was by price brackets. So below you will see the brackets and which companies participated. Specific details will be included on each bracket's write up.

The question I tried to answer is how well do these WordPress hosting services perform? I tested each company on two distinct measures of performance: peak performance and consistency. I've also included a compute and database benchmark based on a WordPress plugin.

All tests were performed on an identical WordPress dummy website with the same plugins except in cases where hosts added extra plugins. Each site was monitored for approximately two months for consistency.

1. LoadStorm

LoadStorm was kind enough to give me resources to perform load testing on their platform and multiple staff members were involved in designing and testing these WordPress hosts. I created identical scripts for each host to load a site, login to the site and browse the site. Logged in users were designed to break some of the caching and better simulate real user load. The amount of users varies by cost.

2. Blitz.io

I used Blitz again to compare against previous results. This tests the static caching of the homepage. I increased the number of users based on monthly cost this time.

3. Uptime (UptimeRobot and StatusCake)

Consistency matters. I wanted to see how well these companies performed over a longer period of time. I used two separate uptime monitoring services over the course of a month to test consistency.

4. WebPageTest.org

WebPageTest with 9 runs, first view only, native connection. I tested from Dulles, Denver, Los Angeles, London, Frankfurt, South Africa, Singapore, Shanghai, Japan, Sydney, Brazil.

5. WPPerformanceTester (free plugin on WordPress.org)

I created a WordPress plugin to benchmark CPU, MySql and WordPress DB performance. The CPU/MySql benchmarks are testing the compute power. The WordPress component tests actually calling $wpdb and executing insert, select, update and delete queries.


Notes - Changes made to Hosting Plans

A2 - VPS Servers can't install WordPress out of the box without extra payment for Softaculous. Disabled recaptcha.

Conetix - disabled WordFence and Stream plugins.

SiteGround - fully enable SuperCacher plugin

GoDaddy - 24 database connection limit increased if you notify them of heavy load

CloudWays - disabled WordFence

Review Signal Ranking Algorithm Update

In a recent article, The Rise and Fall of A Small Orange, it became quite apparent that our ranking algorithm here at Review Signal needed an update. Review Signal launched on September 25, 2012 which was almost 3.5 years ago. At launch, we had data from as early as 2011, which means this site's data is up to 5 years old today. It wasn't an issue back then because the oldest data would be at most, two years old and still relevant.

Today, our older data isn't really as relevant as it once was. A Small Orange exposed that weakness. It was an issue I knew I would have to deal with eventually, but nobody has really made the system fail until now. Since writing about The Rise and Fall of A Small Orange, I've been working hard to figure out a good way to update the ranking algorithm.

The solution I have come up with is a decay function. Older reviews will be worth a fraction of their more recent counterparts.

(1/(ABS(TIMESTAMPDIFF(YEAR, NOW(), max(timestamp)))+1))

This is the mathematical formula that Review Signal will now be using to calculate the value of a review.

An English explanation would be that for every year old the review is, it becomes worth one divided by years old. A one year or less old review would be worth 1/1 or 1.00. A two year old review would be worth 1/2 or 0.5. A 3 year old review would be worth 1/3 or .33 and so on.

This allows old reviews to still be a part of a company's rankings, but with a strong bias towards more recent reviews so that if a company starts performing poorly, it will decline faster in the rankings.

Checkout the full chart of how these changes affect the rankings and ratings of every published company.

Perhaps the most interesting column is how the Overall Ranking changed because of this algorithm update which I have included below. A Small Orange has the biggest change by a wide margin. HostWay lost a lot as well, but it was already at the bottom and the difference between 36% (old) and 27% (new) isn't very meaningful when you only fall two ranking spots.

HostMonster, Arvixe, HostGator, JustHost, BlueHost and some other EIG brands falling a bit more isn't surprising. It does highlight how old reviews were keeping them slightly higher than they should be, but none were ranked particularly well.

WebSynthesis dropping was a bit of a surprise. Still a decent rating at 62%, but a pretty substantial of 7 ranking places which dropped it from 10th to 17th.

On the other end, there is a lot less change upwards. However, Pagely got a nice little boost which jumped it 8 places upwards to 12th.

Then there's MochaHost, which has the dubious honor of jumping up one slot, to not be the absolute worst company we track, which is now Arvixe.

WPPerformanceTester – A WordPress Plugin to Benchmark Server Performance

Everyone who read our most popular blog post, WordPress Hosting Performance Benchmarks may have noticed a new test this year (2015) called WPPerformanceTester. It was something I built during the tests to add a new benchmark to see what the underlying performance of the server the test websites were hosted on. It wasn't hugely meaningful because I had no real basis to compare from except the benchmarks I had just generated. So it really played no role in the actual rankings and outcomes of the testing.

But the vision for it and value has slowly become more apparent. In my testing, Pagely had an unusually slow WordPress benchmark (testing WordPress database functions). It was acknowledged by their team and they have since announced a migration to a newer Amazon technology called Aurora which gave Pagely a 3-4x performance increase.

So without further ado, I'd like to announce WPPerformanceTester is now live on GitHub and licensed under the GPLv3. All problems, errors and issues should be submitted on GitHub.

What Tests Does WPPerformanceTester Run?

  • Math - 100,000 math function tests
  • String Manipulation - 100,000 string manipulation tests
  • Loops - 1,000,000 loop iterations
  • Conditionals - 1,000,000 conditional logic checks
  • MySql (connect, select, version, encode) - basic mysql functions and 1,000,000 ENCODE() iterations
  • $wpdb - 250 insert, select, update and delete operations through $wpdb

Industry Benchmarks

WPPerformanceTester also allows you to see how your server's performance stacks up against our industry benchmark. Our industry benchmark is the average of all submitted test results. After you run WPPerformanceTester, you will have the option to submit the benchmark with or without writing a review of your web host. Please consider submitting without a review so that our benchmark improves. If you feel inclined to write a review, please feel free. They will be published in an upcoming project that ties together many of the projects I've been working on here at Review Signal.

Please Note

WPPerformanceTester is a single node testing tool (if you're running a distributed/clustered system it will not give a complete picture, but only of the servers that execution touches.

Furthermore, WPPerformanceTester is not the be-all and end-all of performance testing or web host quality. Our WordPress Hosting Performance Benchmarks performs a variety of tests and that only gives insight into performance. It doesn't look at customer service quality, pricing, and other important dimensions of a good web hosting service.

WPPerformanceTester should be used as one tool in a performance toolbox. I hope it's valuable and helpful, but please keep in mind the larger picture as well. If you care about service quality, we also maintain the largest web hosting review database. My goal is to cover every aspect, and WPPerformanceTester marks a small step in that direction of being able to give consumers a complete picture of web hosting quality in the WordPress space.

Pagely WordPress Hosting Review


This post is based off WordPress Hosting Performance Benchmarks (2014).



Pagely came in with a title to defend. Pagely was one of the top tier web hosts in our first round of testing and didn't show any signs of struggling. My biggest complaint was SFTP was an addon, which they now include with every account. Performance-wise Pagely was back at it again with another top tier performance.

The Plan

All testing was done on a shared account, the Personal / Business plan.  This plan allows for 1 WordPress site, 5GB disk space, 10GB bandwidth and costs $24/month.



The first performance test was done with LoadStorm. Pagely made it to the final round of testing where 2000 concurrent users were logging into WordPress and browsing the test site. The test was designed to test non-cached performance by logging users into WordPress. It caused many hosting setups to crumble. You can see Pagely's result in this graph (click on it to play with the interactive results):



Pagely did well on this test. There was one error total which caused a response time spike (blue line in the graph). Other than a single error, the performance was impeccable.


The second load test that was run on Pagely was Blitz. Blitz was used to test cached performance. It simply requested the home page from 1-2000 times per second.


Pagely's Blitz result was exemplary. There were 43 timeouts and errors combined. There was a near flat response time which means it had no issues at all. Pagely didn't blink at this test, as expected based on their performance last time on this test. Full Blitz Results (PDF)


Two third-party uptime monitoring services (StatusCake and UptimeRobot) tracked the test site for a month. The results for Pagely were 99.95% and 100% uptime. It's hard to complain about those numbers or find any issue with Pagely's uptime.


“WebPagetest is an open source project that is primarily being developed and supported by Google as part of our efforts to make the web faster.” WebPageTest grades performance and allows you to run tests from multiple locations simulating real users. Pagely was tested from Dulles, VA, Miami, FL, Denver, CO, and Los Angeles, CA.

Company Dulles,VA Miami, FL Denver, CO Los Angeles, CA Average
Pagely 6.831 0.86 0.913 0.709 2.32825

Pagely was the only company that had any issue with the WebPageTest component of our testing. The test from Dulles had bizarrely high load times for no explicable reason. The other locations were all sub one second, so I dismissed it as a real issue because it's likely some fluke networking issue. But there was a weird networking issue.


Pagely easily defended its title as one of the top tier WordPress hosts. They handled the Load Storm test with 1 error. Blitz results stayed similar to the last run. They handled more hits, but had a few more errors+timeouts (1 last time, 43 this time). If performance is the name of the game, Pagely continues to be at the forefront.

Introducing Pagely and FlyWheel

I am happy to announce two new hosts on Review Signal today.

One of them was a long time in coming, Pagely. The original managed WordPress hosting company. In my original managed WordPress hosting performance benchmarks, Pagely came out at the top - having no trouble with any of the tests I threw at their services.



It's a bit disappointing to see that their reviews don't quite match their performance. From what I can tell, it looks like they've struggled with some major outages in the past. However, there is an upward trend in opinions about them. Their performance is top notch, it would be great to see the rest of the service catch up.

Our second addition to Review Signal is FlyWheel which has an astounding 95% Overall Rating. FlyWheel is another managed WordPress hosting service built on top of Digital Ocean. I don't think I've ever seen a company have such positive reviews. It's a struggle to find anyone saying something negative about them. It's wonderful see such positive reviews for a new company.


I hope they can keep it up, but my past experience says all the companies which start out so remarkably strong generally tend to come down to more 'normal' levels in the 70%ish range. Their competitors WPEngine (82% -> 73%) and WebSynthesis (83% -> 76%) both did. Also the company they were built on top of, Digital Ocean, went from 81% to 76%. Great service seems like the hardest problem to scale for a web hosting company. I hope FlyWheel can break the rules and continue it's streak of excellence.

Managed WordPress Hosting Showdown – Performance Benchmarks Comparison

UPDATE: Round 2 of Testing (November 2014) is now available.

WordPress as a platform has become the most popular CMS around, claiming to power almost 19% of the web. As a result, Managed WordPress hosting has become a very popular niche. Many companies in the managed WordPress space are charging a very high premium over the traditional shared web hosting providers. So beyond the marketing speak, what are you really getting? Most promise to make your life easier with features like automatic updates, backups, and security. They also claim to have great performance. It's hard to test objectively the ease-of-use features. But we can measure performance. There weren't many performance benchmarks that I could find, and the ones I could were not very thorough. So I began by designing my own set of testing.

Companies Tested

A Small Orange* [Reviews]
Digital Ocean [Reviews]
GoDaddy* [Reviews]
SiteGround*† [Reviews]
WebSynthesis* [Reviews]
WPEngine [Reviews]

*Company donated an account to test on. I checked to make sure I was on what appeared to be a normal server. GoDaddy had over 3000 domains on the same IP. SiteGround had 887 domains. A Small Orange was a VPS, so it should be isolated. Pressable and WebSynthesis didn't have any accounts on the same IP. I am not sure how isolated they are in their environments.

†Tests were performed with SiteGround's proprietary SuperCacher module turned on fully unless otherwise specified.

The Products

I created a comparison chart of all the companies and the product used in this test. It was mostly the basic/cheapest offer with the exception of SiteGround, because their cheapest hosting plan didn't have full WordPress caching built in, but it was still very much within the price range of other offers.

(Click to see full table)



The question I tried to answer is how well do these WordPress hosting services perform? I tested each company on two distinct measures of performance: peak performance and consistency.

1. Blitz.io

Load testing from the most well known load testing service. First test was 60 seconds, from 8 locations each scaling from 1-125 concurrent users (total 1000 users). For this test each one was tested with identical theme (twenty fourteen) and the out of the box configuration. The second test was 60 seconds, from 2 locations (Virginia/California) scaling from 1-1000 (total 2000 users). The configuration of each site was identical with Customizr theme and plugins.

2. Uptime (UptimeRobot and Uptime - a node.js/mongo project)

Consistency matters. I wanted to see how well these companies performed over a longer period of time. I used two separate uptime monitoring services: one existing third party service and one open source project.

3. WebPageTest.org

"WebPagetest is an open source project that is primarily being developed and supported by Google as part of our efforts to make the web faster." WebPageTest grades performance and allows you to run tests from multiple locations simulating real users. I tested from Dulles, VA, Miami, FL, Denver, CO, and Los Angeles, CA.

4. Unnamed Load Testing Service*

This service asked to remain nameless in this article. They do natural load testing and are in beta. I tested each WordPress host with the same theme (twenty fourteen) and the out of the box configuration for this test. I ran into some issues with this service which I will discuss later.

Background Information

Before I go over the results I wanted to explain and discuss a few things. Every provider I tested had the latest version of WordPress installed. Every plugin that came with it was also up to date with the exception of GoDaddy which had an older version of JetPack included (17 days out of date when I first setup).

I had some trouble getting set up on A Small Orange, the signup email was stuck in gmail's spam filter. I also found a potentially minor security issue in their customer system which they promptly responded to and fixed. I also had to specifically ask for the customized WordPress LEMP stack to be installed on my VPS.

GoDaddy stores SFTP and other critical details on a separate area away from your main GoDaddy account and WordPress admin (gateway.godaddy.com for anyone stuck looking).

I ran into issues with Pressable's CNAME redirect. It seemed to cache a coming soon page and didn't resolve itself by clearing any cache I could find. It resolved itself over a day or so, but being stuck with a coming soon page wasn't a pleasant first experience.

SiteGround includes CloudFlare but I never got it working, it failed to configure on www. So I couldn't conduct the test with it enabled.

Pagely charges you extra for SFTP access (which I didn't pay for and made my own life a living hell while trying to do this test).

WebSynthesis came pre-installed with two themes that were out of date.



 Test 1. 1-125 Concurrent Users from 8 Locations over 60 seconds (Gallery)

 Discussion of Blitz Test 1 Results

The first thing I must note here is that two companies got absolutely destroyed by this test: Digital Ocean and A Small Orange.

My Digital Ocean VPS just died repeatedly. MySql died and needed to be manually restarted. I thought it was a bad instance, so I spun up another and got the same result. I even tried installing a caching plugin to see if I could get any performance out of their WordPress stack. I had absolutely no luck. Given this result, I eliminated Digital Ocean from the rest of my testing. You can run high performance WordPress sites on Digital Ocean (Review Signal's blog is running on one currently), but it requires knowing what you're doing and isn't recommended for people looking for managed WordPress hosting. Digital Ocean is a self-managed VPS provider; it's not for beginners or those who need managed support of their WordPress site. I included Digital Ocean to see how their offer would fare against specialized companies. The short answer is, it doesn't compare, at all.

Another out-of-the-box install with A Small Orange got crushed by this test too. After dconsulting with A Small Orange support, it became apparent I wasn't on their customized WordPress setup. I asked for it to be installed and all further tests were on this much more performant setup. You will see two sets of results for ASO, the normal and the LEMP stack, which is their high performance setup. One thing to note is that ASO offers less management on their customized WordPress setup because it no longer uses cPanel.

The lesson here is that WordPress, out-of-the-box with a LAMP stack, performs pretty badly. For a personal blog with low traffic, it probably won't matter, but for a site with any substantial amount of traffic, it will most likely crumble.

Who performed without any major issues?

A Small Orange (from now on, anytime I talk about ASO, it's about the specialized WordPress setup), Pagely, and SiteGround. Each of these companies had stable response times and few to no errors.

Who had some issues?

GoDaddy had an issue with errors in the middle of the test around 400 users but seemed to gracefully scale upwards without any difficulty and maintained steady load times and stopped erroring. Pressable's response times were a bit varied. Pressable didn't seem to have much trouble with the traffic because it had zero errors and minimal timeouts. WPEngine seemed to have a weird connection timeout issue around 600 users that resolved itself fairly quickly. WebSynthesis seemed to cap out at around 400 users/second with a few bursts. The response time remained steady and it was erroring (connection reset) instead of timing out. WebSynthesis support told me "We analyzed the logs on the server and some of your requests are not being cached as your tests are throwing over 14K symbols in a single URL. This is not realistic for normal use cases of WordPress." Nevertheless, they made a tweak to the nginx (webserver) config, and I tested it again in test 2.

Test 1. Quick Results Table

Success Errors Timeouts Avg Hits/second Avg Response (ms)
ASO 23788 18 2 396 241
GoDaddy 23962 165 0 399 227
Pagely 20132 1 0 336 459
Pressable 21033 0 19 351 412
SiteGround 19672 0 0 328 495
WebSynthesis 19995 4224 5 333 246
WPEngine 20512 192 196 342 395

GoDaddy, despite their small hiccups, managed to have the best average response time to 8 servers distributed across 5 continents (Virginia, Oregon, California, Singapore, Japan, Brazil, Australia, Ireland). Furthermore, they also managed to serve the most hits.

SiteGround had the slowest average response and lowest hits/second but also didn't have a single error or timeout and the response was consistent throughout the test.

A Small Orange's performance was stunningly consistent. The fastest response was 238ms and the slowest was 244ms, a difference of 6ms over nearly 24,000 requests. They were just barely behind GoDaddy in hits and average response.

Overall, other than WebSynthesis, no host seemed to have serious difficulty with this test.


 Test 2. 1-1000 Concurrent Users from 2 Locations over 60 seconds (Gallery)

Discussion of Blitz Test 2 Results

This test was designed to see just how much traffic these web hosts can handle. Blitz increased their pricing for multiple server locations while I was running this test. I had to reduce server locations from 8 down to 2 locations with higher user counts instead. The response times may be less meaningful, but I picked Virginia and California so that the test locations were on opposite sides of the US. I believe every server tested was in the US, so hopefully that was somewhat balanced, but the average response time may mean less than the stability of the response time.

Who performed without any major issues?


Who had some issues?

A Small Orange's setup definitely couldn't scale all the way up. Response times started increasing with increased users as did errors/timeouts. GoDaddy had some bizarre spikes that look similar to the one I saw in test 1, except three of them this time. Despite this, they pushed the most successful hits again and had the best ping of hosts that didn't completely error out. Pressable had some spikey performance similar to GoDaddy. Pressable pushed a lot of successful requests and did recover from the spikes. SiteGround hit a major spike but then seemed to kick into high gear and performed even better and finished out the test exceptionally strong and stable. WebSynthesis seemed to cap out at around 400 users/second with a few bursts again. The response time remained fairly steady and it was erroring (connection reset) instead of timing out again. WPEngine's response times got worse as the load increased and timeouts started to increase as well.

I included a screenshot from my uptime monitoring system. It's checking each host every 5 seconds, and I highlighted the hour in which all the tests took place. You can see some large spikes for companies that seemed to have latency struggles.


Test 2. Quick Results Table

Success Errors Timeouts Hits/second Avg Response (ms) Max Hit Rate (per second)
ASO 27057 777 518 451 739 597
GoDaddy 49711 685 1 829 148 1750
Pagely 48228 0 1 804 216 1580
Pressable 43815 503 9 730 271 1466
SiteGround 48735 12 19 812 263 1708
WebSynthesis 20855 35773 0 348 120 763
WPEngine 39784 25 1008 663 304 1149

GoDaddy seemed to have the best peak performance again. SiteGround and Pagely seemed to handle the load fantastically and didn't show any signs of performance issues (again). With the exception of A Small Orange, every host saw an improvement in average response time. As I wrote earlier, this may be because they were tested only from US locations. That caveat aside, the response times are a lot closer together and look pretty good for US based visitors. Still, this test also started to raise questions about many web hosts' ability to handle a heavy traffic load.

WebSynthesis Response to ECONNRESET Errors

WebSynthesis ran into the same issue in both tests, a strange ECONNRESET error. Suspecting something may be blocking the test requests' as a security measure, I asked them to investigate. They made a change to their nginx config after the initial set of testing and wrote back "we made adjustments to handle the types of URLs you were hitting us with.  We did review our logs and do not see these in production thus will not put these kinds of changes in production as we feel they are unrealistic." Here are the results:

WebSynthesis2-blitz WebSynthesis2 (Download Full Report WebSynthesis2.pdf)

The new WebSynthesis results were pretty impressive. Average ping of 123ms (3ms slower than initial test), 871 hits/second average, 1704 hits/second and with only 94 errors (ECONNRESET again). The original tests did not suggest that either the hardware or software was starting to buckle. But the configuration change does indicate that they were probably blocking some of the requests. Load testing tools can't fully emulate users (they generally come from only a couple of machines) and it's conceivable that some security measures are triggered by their unusual behavior. Since I am testing these companies out of the box, I am leaving this result separate where support got involved and changed configuration settings.


What is often more important than peak performance is how well a service does on average. To test this, I used two services: UptimeRobot and a NodeJS project called Uptime.

UptimeRobot Results

Monitored HTTP and Ping every 5 minutes. This was over a 10 day span.

ASO 1 1
GoDaddy 0.9979 -
Pagely 0.9862 -
Pressable 0.9995 1
SiteGround 0.9993 1
WebSynthesis 1 1
WPEngine 1 1

A Small Orange, WebSynthesis and WPEngine showed no downtime. Every server responded to pings 100% of the time with the exception of GoDaddy and Pagely which seemed to be blocking pings to the server (at least from UptimeRobot).

Pagely's downtime was mostly my own doing (3 hours), when I was editing a template  to use some of these testing services. Only 5 minutes of the downtime was unrelated to that incident.

GoDaddy had 28 minutes of downtime. SiteGround had 9 minutes. Pressable had 5 minutes.

When you account for my screwup, only GoDaddy shows up under the 99.9% uptime threshold.

Uptime (nodejs) Results

Uptime was configured to perform an HTTP check every 5 seconds on each host with a 1500ms slow threshold. This was executed from a Digital Ocean VPS in NYC.

Responsiveness is defined as the percentage of pings above slow threshold over the period. Availability is the uptime percentage.

Availability (%) Downtime (m) Response Time (ms) Responsiveness (%)
ASO 99.998 1 204 99.97
GoDaddy 99.963 17 309 99.679
Pagely 99.998 1 237 99.974
Pressable 99.914 39 727 90.87
SiteGround 99.997 1 206 99.616
WebSynthesis 99.994 3 97 99.727
WPEngine 99.965 16 209 99.819

Nobody had a perfect record although four companies (A Small Orange, Pagely, SiteGround and WebSynthesis) were above the 99.99% uptime marker. The rest were still all above 99.9%. The most worrisome result was Pressable because they had the most downtime and a very high average response time. This might be caused by the monitoring server being far away from their server. Below is a detailed graph of the response times:


The lowest ping I saw was around 172ms and the relatively consistent bottom line of pings at around 300ms is reasonable. However, inconsistent performance with high spikes results in a very high average. Every other company had a fairly smooth graph in comparison. They show an occasional spike and/or some small variance (<100ms) between response at the base line, but nobody came close to a graph like Pressable's. The next most interesting is A Small Orange's graph:


Though within reasonable response times, it has a spike and a weird pattern bouncing between around 170ms and 270ms.

Giving Pressable the benefit of the doubt, I signed up for Pingdom and monitored what their service saw. This was done with 1 minute resolution.pressable_pingdom_uptime



The pings varied pretty wildly, the highest being 2680ms and lowest 2150, a 530ms difference. And that was based on hourly averages; the variance within each hour may have been much greater. It would seem to corroborate the results from the Uptime script I was running, i.e. performance fluctuates a lot.



Every test was run with the settings: Chrome Browser, 9 Runs, native connection (no traffic shaping), first view only. This was tested against the default install from every company. I also tested SiteGround's multiple levels of their SuperCache technology from one location to see how much it improved performance. SuperCache was left on for all the other tests performed. You will also notice the original A Small Orange and the WordPress optimized LEMP stack. Digital Ocean hadn't completely failed out at this point yet either.

Company Dulles,VA (s) Miami, FL (s) Denver, CO (s) Los Angeles, CA (s) Average Load (s)
A Small Orange 1.894 2.035 2.381 1.648 1.9895
ASO Lemp 0.85 0.961 1.056 0.665 0.883
Digital Ocean 1.245 0.95 1.419 0.924 1.1345
GoDaddy 0.94 1.208 1.229 0.671 1.012
Pressable 0.642 1.174 1.721 0.981 1.1295
SiteGround 1.073 1.327 1.682 1.353 1.35875
SiteGround (Varnish Dynamic Cache) 0.732
SiteGround (Varnish Dynamic Cache, Memcached) 0.725
SiteGround (PageSpeed, Memcached) 1.216
WPEngine 0.812 1.235 1.06 1.08 1.04675
Pagely 0.924 1.083 1.46 0.748 1.05375
WebSynthesis 0.616 1.021 1.516 1.116 1.06725

You can see a huge performance difference in A Small Orange's default cPanel install and their optimized LEMP stack. Load times were reduced by more than half from every location. That should convince you that optimizing WordPress can dramatically improve performance. To a lesser degree, you can see it happen when SiteGround's various SuperCache options are turned on.

A Small Orange's LEMP stack leads the pack here. However, it's amazing how close the performance of most of these companies was on this test.



Every service seems to have their issues somewhere. I try to avoid injecting my personal opinion and bias as much as possible. So I won't be ranking or outright saying any single company is the best. Some providers did exceptionally well and tended to clump together performance-wise, I will call those the top tier providers. This top tier designation is related to performance only and from the results of these tests. What each of these companies is offering is different and may best suit different audiences depending on a variety of factors beyond performance, such as features, price, support, and scale (I only tested entry level plans). But I will provide a short summary and discussion of the results for each provider.

A Small Orange

Once I moved away from the stock WordPress install on a normal VPS to their specialized LEMP WordPress VPS, it was a much better experience. Their uptime was near perfect on both services (1 minute of downtime total measured between them). The first load test it performed incredibly well and was 2nd by only a few requests per second. However, ASO did buckle under the heavier load test but it didn't fail out and managed to respond to most requests (including uptime monitoring) during the whole event. While their performance didn't scale as well as most of the competitors, I did receive a lot of support from them and it was quite responsive, in-line with what I would expect from a company that has one of the highest support ratings.

Digital Ocean

They are not in the same business as the rest of these companies. I added them because I wanted to see how well a stock install of WordPress would compete with pretty good hardware that's low cost (SSD backed VPS). The results here aren't a knock on their service at all. As I said earlier, this blog is running on a Digital Ocean VPS. The difference is I have spent many hours configuring it myself to be somewhat high performance. Digital Ocean is designed for people who can administrate their own servers. If you need managed WordPress hosting, stick to companies that are managing WordPress for you. If you're comfortable and want to do it yourself, these guys have one of the highest rated companies that we track.


This whole test started from a statement made by Jeff King, a senior vice president at GoDaddy and GM of their hosting division. He wrote to me, "The new products are top of the market (really, you can’t get faster WordPress anywhere now) and we’re just beginning."  Challenge accepted.

GoDaddy surprised me, and in a good way. They have a pretty bad reputation in the web community and it shows on this site where their overall score is below 50%. Yet, their WordPress hosting kept up or led the pack in some of the performance tests. In both Blitz.io load tests, out-of-the-box, GoDaddy had the highest number of successful requests, the highest number of concurrent users, and either 1st or 2nd in average response time.  (WebSynthesis's performance did beat them when their support investigated connection resets) There were some weird performance bumps during the load tests, but nothing major. The biggest blot in terms of performance was on their uptime. They had the most downtime (28 minutes) of any of the companies tracked in UptimeRobot's monitoring (which ran longer than my second Uptime monitoring setup). But it was still 99.8% uptime, not a huge knock.

Overall, I would say GoDaddy delivered on their claim, performance wise. They appear to be in the top tier of specialized WordPress hosting companies. Given their price, I think they have the potential to push down pricing on most of their competitors who charge 3-4 times what GoDaddy charges. If we take a more holistic view, beyond performance, they still don't have all the tools to cater to the different niches that the specialized companies are competing for (although there were some hints dropped that things like Git, Staging Environments and more were coming soon). And then there is a branding problem they are trying to overcome. But GoDaddy is definitely doing some things very right and should make the managed WordPress hosting space very interesting.


Pagely's performance didn't ever seem to get affected by any tests. They had a mere 5 minutes of downtime. The load testing services never seemed to cause any stress on their system. It was an impressively consistent performance. They didn't have the highest peak performance on the load tests, but they had a flat response time and only a single error or timeout in each blitz load test. One thing that irritated me about their offer was charging extra for SFTP access. Every other company included this for free and it's generally a given with a web hosting service. Still, a very impressive performance by Pagely, they are definitely in the top tier.


Pressable had some issues during this test. I am not sure why but there was a very strange issue where performance seemed to repeatedly spike throughout my entire testing session. When it was good, it was performing at a level consistent with the top tier providers. The problem was, it wasn't always good. On the large Blitz load test there was consistent performance except for two spikes, which put it behind the front of the pack. It caused low responsiveness scores and potentially some downtime calculations as well. The foundation of a top tier provider is there, and generously open sourced on GitHub. They just need to sort out this weird performance spikiness issue.


Another very pleasant surprise in SiteGround. Not only are you getting cPanel hosting, you're getting top tier WordPress performance once you fully enable their SuperCacher plugin. They are one of the most well liked companies we track and have some of the best rated support. I honestly didn't know they were offering such high performance WordPress hosting. They didn't have the absolute fastest responses or push the highest concurrent users but they kept pace. They had one of the stranger graphs on the heavy load test, for some reason the performance got even better after a big spike. They had excellent uptime at above 99.9% measured by both services. Like GoDaddy, SiteGround looks like they could make this space interesting with a $7.95 plan performing on par with plans 3-4x its cost. While I didn't get to try some of the more developer-centric features like a staging environment and Git, they are available on a plan that's as little as 50% of the cost of the competitors at $14.95. Definitely in the top tier of managed WordPress providers.


These guys are harder to evaluate. Their uptime was excellent: either perfect or upwards of 99.9% as measured by the two services. The load testing ran into a weird ECONNRESET error. Their support was very helpful and made some configuration changes that seemed to allow the load testing service through. Once they did that, they outperformed every provider on almost every metric, highest average hits/second, fastest response and most successful hits with relatively flat response times. As I wrote in my discussion about them, load testing tools aren't a perfect emulation of real users. But it looked like it was running into a security rule rather than actual strain on the service. If that assumption is correct, these guys are truly a top tier provider.


WPEngine had some issues. Uptime was not one of them, they were perfect or upwards of 99.9% in that department. However, their performance shortcomings became apparent during the load tests. They had the most errors and timeouts, besides WebSynthesis, in the first test and seemed to buckle under the load in the second test with rising errors and timeouts and slower response times. When WPEngine was first listed here on Review Signal, they had the highest rating of any company. They've fallen a bit since then but WPEngine still remains near the front of the pack. They have a strong brand and seem to be doing some things right. They have some features that few other providers have, but this test was mostly about performance. In that department, they didn't quite match the level of performance that some of their competitors reached.

I didn't get to conduct a full test with this service because I may have caused the entire service to crash during testing. This table is showing 2 tests, on average response and whether failures occurred (any type of failures). The second test is what caused the service to crash and is incomplete. The first test was 500 users/second from 1 machine and the second was 8000 users/second from 40 machines. The response times were pretty slow all around, and SiteGround seemed to have some major issues with this test. I am unsure as to why, I re-ran the first test again later and it seemed to handle it without any failures (errors) on the second run. The testing system is in beta and it's really hard to know what happened. SiteGround seemed to handle Blitz's heavier test without issue and the second test here went fine. Hard to know if there was really an issue on SiteGround's end or the testing service. The heavy test was interesting, WebSynthesis ended up being the fastest which is a similar result to the Blitz.io test once they fixed the nginx config. Perhaps this load test wasn't triggering any of their security measures? I could not complete the testing because the system went down prematurely.

I am not sure if there are useful inferences to be drawn from these tests. I was asked not to name the service because of the issues encountered but I wanted to include the partial results here in case someone did find some value in looking at the numbers.

I actually tried a third load testing service that was also in beta and it never was able to fully run the tests either. I am starting to feel like load testing kryptonite.

Thank You

First off, I want to thank the companies that agreed to participate voluntarily. I had nothing but pleasant experiences dealing with the people at each company. A few even took it a step beyond and offered a lot of help and insight about how this test might be conducted. There was a surprising amount of consistency of views about what and how to measure performance offered. A few of the individuals who stood out the most:

David Koopman at GoDaddy for his insights on performance and testing.

Vid Luther at Pressable was incredibly helpful and knowledgeable about performance. He's even written a great article here about performance. He also helped get at least one other company on board for testing and for that, I am thankful as well.

Tina Kesova at Siteground has always been helpful and this test was no exception. She had SiteGround on board almost instantly when I just mentioned the seed of the idea back in November 2013.

A few friends of mine also helped in figuring out how to perform these tests and dealing with some of the technical challenges in benchmarking. Dave Lo, Eric Silverberg and Samuel Reed all offered their advice and helped me make the design of the tests as fair as possible.

A special thanks goes to people who read drafts of this article and provided feedback including Andrey Tarantsov, JR Harrel and my dad.

Anyone else I missed, I am sorry, and thank you too.
