Today updated this blog’s Centmin Mod LEMP stack PHP-FPM to PHP 7.0.1 with added PHP Redis PHP Extension support and enabled Nginx level Redis caching + Redis Object Caching. The switch from WordPress Super Cache plugin to this WordPress Redis caching combination will result in much faster site for this 2GB DigitalOcean KVM VPS. Below are the results for Blitz.io & Loader.io both with 10,000 user benchmark stress test for this blog.

Blitz.io 10,000 user California test run on this 2GB DigitalOcean KVM VPS resulted in 302.67 million hits/day with a peak of around 5,122 hits/second and average of 3,503 hits/second.
Next up is Loader.io 10,000 user test on their free plan. The 10,000 users where distributed over 1 minute test duration so not concurrent. Note Loader.io’s main test servers are located in US East coast, while my blog is located in Fremont, California on US West coast hence the difference in average response time due to geographic distance differences. Average response time for this test was 74ms.
And finally Loader.io test with a maintained 0 to 10,000 user load over 60 minutes as opposed to distributed 10,000 user load over 60 minutes. Average response time for this test was 928ms.
