Pantheon participated for the fourth time in our WordPress Hosting Performance Benchmarks (2018). Last year Pantheon earned two Top Tier awards. This review is based off the results of this years test.
Pantheon stepped up their game this year and earned three Top Tier awards and one honorable mention. Pantheon also has the honor of being the highest rated company on Review Signal for reviews based on customer opinions (84%).

The Load Storm test is designed to simulate real users coming to the site, logging in and browsing the site bursting some of the caching mechanisms typically found on managed WordPress hosts.
Pantheon overall did very well. The only issue was in the $200-500 price range it started to show signs of load. It wasn't a huge issue and the plan still earned an honorable mention in the price tier.

The Load Impact test makes sure static caching is effective so that if a page gets a lot of traffic the site will keep responding without issue.
Pantheon aced the LoadImpact tests across every price tier. Zero errors on all four tests and maintained a sub 200 millisecond response time average. Couldn't ask for a better performance.
Not a whole lot to say here other than excellent. 100% uptime across the board except one monitor out of two showing 99.97%.

The WPT tests were pretty phenomenal, I rarely comment on these because it's rare a company stands out so much. Once you left the US, Pantheon was often the fastest amongst their peers. Their global coverage appears to be top notch out of the box.

The WPPerformanceTester results were pretty consistent. Since it's supposed to be the same platform that scales up, the results looking similar seems to make sense. The slight improvement in PHP bench scores as you scale is nice, but without a lot of repeated testing, unclear if that's by design or just a happy coincidence.
Another year, another fabulous performance from Pantheon. Not only are they the highest rated company on Review Signal's reviews - they consistently earn top tier performance awards in our testing. They stepped up their game from last year and earned an extra Top Tier performance award and an honorable mention. Their global response times were maybe the most impressive feature. They earned fastest average response time in 3/4 tiers on Load Impact and 2/4 on Load Storm, along with often having the fastest response time in their price tiers on WebPageTest. Overall, it was a pretty impressive performance from Pantheon this year.
