Kinsta Review (2018)

Kinsta participated for the fourth time in our WordPress Hosting Performance Benchmarks (2018). This review is based off the results of that test. This year Kinsta participated in the 25-50, 51-100, 101-200, 201-500, and Enterprise price tiers.

In the previous test, Kinsta earned Top Tier status in all four price brackets it entered.  In 2018, Kinsta started offering cheaper plans and has competed in an additional, lower price tier.

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.

Kinsta aced the Load Storm tests across every tier. Zero errors in multiple price tiers and minimal errors in the others. The response times were kept fast and stable. It scaled up from the smallest test to Enterprise test without issue.

Load Impact

Enterprise 1367747 0 73.4 0.802 1120 2540

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.

Perfection. Zero errors across 5 separate tests.

The WPPerformanceTester results looked normal. The WP Bench results stood out though. The database connections are consistently very fast compared to their competitors at higher price tiers when plans tend to run separate and/or multiple database servers.

Conclusion

Kinsta earned itself five Top Tier WordPress Hosting Performance Awards in 2018. It had perfect uptime across every plan. It had zero errors on Load Impact. It had 2/5 Load Storm tests without any errors and only 52 errors total from 3.685 million requests. No signs of stress showed on any test. Kinsta has consistently brought their A game to WordPress Hosting Performance Benchmarks, this year was no exception. It's nice to see them offering newer, cheaper plans that allow people on smaller budgets access their offerings. A huge congratulations to them for earning the most Top Tier Hosting Performance awards of any company in 2018.
