hello all i'm planning to run whmcs on centminmod, anyone here using centminmod for whmcs too? do opcache, xcache, apc, memchache improve whmcs performance? since whmcs script is encrypted using ioncube? so php cache is useless? i have installed centminmod and opcache is enabled by default, are xcache, apc enabled, memcached by default too? how to disable/remove them?
