Since i`m building managed WordPress hosting, i already made some benchmarks before i decide witch technology to go. I tested nginx, ols, varnish with
loader.io and i was so surprised that ols outperform all technologies. Interesting thing was that with nginx and varnish i was receiving connection timeouts when high load and with ols, just more wait response time. However i don`t have prove about this but ill make new tests for:
1. OLS + hhvm + wordpress + w3tc + apcu
2. OLS + lsapi php + wordpress + w3tc + apcu
3. OLS + ols cache
Give me 1 day :)
