Flywheel, GridPane, Jelastic, Pantheon, Pressable, Presslabs, Seravo, Servebolt and WPVIP all handled this test without issue. It's impressive how the average response time for every company was below 200ms.

No company struggled with the Load Impact test. Jelastic had a very strange looking graph with response times bouncing up and down, possibly an auto scaling issue? GridPane's graph looked like there was an increasing in load but the peak was under 300ms, it really isn't an issue.

Uptime Testing Results

Uptime is monitored by two companies: HetrixTools and Uptime Robot. A self hosted monitor was also run in case there was a major discrepancy between the two third party monitors.

No companies had any uptime issues.

Servebolt also had a discrepancy between UptimeRobot and StatusCake uptime. One showed a very low 99.581 and the other 100. The third monitor I setup showed 99.99%, so I went with the StatusCake number.

WPPerformanceTester Testing Results

WPPerformanceTester performs two benchmarks. One is a WordPress (WP Bench) and the other is a PHP Bench. WP Bench measures how many WP queries per second and higher tends to be better (varies considerably by architecture). PHP Bench performs a lot of computational and some database operations which are measured in seconds to complete. Lower PHP Bench is better.

Discussion

Servebolt stood out being the fastest PHP Bench and WP Bench. GridPane, Pressable, Presslabs and Seravo all had faster PHP bench scores than the second fastest company last year (Presslabs); so it's nice to see the whole field getting faster.

*GridPane.com couldn't run the WPPerformanceTester plugin because of the database layer they run wasn't compatible (LudicrousDB). The same commands were executed manually that the WPPerformanceTester does against the system to replicate the numbers.

SSL Testing Results

The tool is available at https://www.ssllabs.com/ssltest/

GridPane, Pantheon, Presslabs and Seravo all earned A+ ratings. Every single B grade was for the following reason according to Qualsys: "This server supports TLS 1.0 and TLS 1.1. Grade capped to B."

Conclusion

There are two levels of recognition awarded to companies that participate in the tests. There is no ‘best’ declared, it’s simply tiered, it’s hard to come up with an objective ranking system because of the complex nature of hosting. These tests also don’t take into account outside factors such as reviews, support, and features. It is simply testing performance as described in the methodology.

Top Tier

This year's Top Tier WordPress Hosting Performance Award goes to the following companies who showed virtually no signs of struggle during the testing.

Honorable Mention

The following companies earned Honorable Mention status because they did very well and had a minor issue or two holding them back from earning Top Tier status.

No company achieved this status.
