WordPress Super Cache Benchmark – Locust IO Load Testing

Wordpress Super Cache Benchmark - Locust IO Load Testing

This blog post was migrated from old wordpress7.centminmod.com site prior to it’s closure. WordPress Super Cache benchmark and load testing continues. I came across Locust load testing tool which is an open source Python based load testing tool which allows distributed master and slave load testing against a target web site (this blog). I setup a master & slave Locust load tester server cluster with 2 dedicated servers I have – Las Vegas, Nevada Intel Xeon E3-1240v3 32GB, 250GB SSD server as master Locust server and a Montreal, Canada Intel Xeon Xeon E3-1245v2 32GB, 3x120GB SSD server as slave.

WordPress Super Cache Benchmark – Siege http load testing

Wordpress Super Cache Benchmark - Siege http load testing

This blog post was migrated from old wordpress7.centminmod.com site prior to it’s closure. Running more load testing benchmarks against this blog for WordPress Super Cache benchmarks. This time using Siege http load testing tool. Centmin Mod LEMP web stack installer already includes installation of Siege benchmark tool by default, so makes testing quite easy. You would need to run Siege benchmark tool from a separate server from the target test web server/site you want to test as Siege uses server resources itself (cpu and memory).

WordPress Super Cache Benchmarks (Blitz.io load test) 237 million hits/day

blitz.io

This blog post was migrated from old wordpress7.centminmod.com site prior to it’s closure. Third group of WordPress Super Cache benchmarks this time with some NewRelic server stats added. Blitz.io load tested this WordPress blog’s index page with 8000 users over 60 seconds with California region. This time no TCP errors as I did a few optimisation tweaks including lowering the memory allocation to MariaDB MySQL to free up more memory for Nginx and PHP-FPM (below memory usage charts show this as a dip in peak memory usage).

WordPress Super Cache in action + Centmin Mod LEMP web stack  = 237+ million hits/day  or 7.12 billion hits per month with peak of 4,158 hits/second and an average of 2,748 hits/second. Average response time was 298ms with slowest being 882ms once it hit 7664 user mark.
