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.
