More WordPress Super Cache benchmarks using Loadimpact.com free account (limited to 250 VU – virtual user load tests). For load testing I set to 250 VUs and 5 minute load testing duration which is the maximum available through the free Loadimpact.com account.
This WordPress blog was installed using my Centmin Mod WordPress Auto Installer script, so I am running a variety of WordPress Super Cache benchmarks to see how it holds up under various loads on a 2GB KVM based DigitalOcean KBM VPS + CentOS 7.0 using Centmin Mod LEMP web stack and PHP 7.0.0-dev (PHP NG).
User load time at 250 VUs was around 35.09 ms
CPU load average was 0.256 / 2 = 0.128
Nginx active connections was around 59
Nginx connection Accept rate was 12.5 connections/sec

- Centmin Mod .08 beta release
- Nginx 1.7.7
