Historical Performance Summary
- Top Tier - Honorable Mention - No award
2020 WordPress Results
High Availability managed the perfect load tests with zero errors. Near perfect uptime of 99.997% and 100% cap off a Top Tier performance.
Formerly Incendia Web Works, this multiple time participant is back in the Top Tier. Their 99.999% and 100% uptimes combined with doing well on the load tests showed they are highly available. The one test which made it clear that they were doing something different at this tier is the WPPerformanceTester WP Bench test where they have a very low score. One reason I don't use it as a meaningful metric is because of how architectures might impact the results. Latency between the database(s) and the web server will cause dramatic differences in the results and the load tests made it clear how real world performance may not correlate strictly with the WP bench result against other architectures. Great job by HighAvailability this year earning Top Tier status.
100% uptime is really nice to see. 0 Load Impact errors and a miniscule 18 errors on Load Storm wrap up an overall excellent performance, well deserving of Top Tier honors.
Load Storm is designed to simulate real users visiting the site, logging in and browsing. It tests uncached performance.
K6 is designed to test cached performance by repeatedly requesting the homepage.
WebPageTest fully loads the homepage and records how long it takes from 12 different locations around the world.
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.
WPPerformanceTester performs two benchmarks. One is a WordPress (WP Bench) and the other a PHP benchmark. 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. WP Bench is red in the chart, PHP Bench is blue.
