PHP performance: oPcache Control Panels

OPcache is a PHP extension that improves PHP performance by storing precompiled script bytecode in shared memory, thereby removing the need for PHP to load and parse scripts on each request. The extension is built-in for PHP 5.5+. If you want to improve PHP performance, the first step should be to use PHP 8+, which is faster than PHP 7. In any case, using OPcache will speed up scripts ~ two times faster!

PHP oPcache Control Panels

opcache.revalidate_freq = 10
(default “2”) How often (in seconds) to check file timestamps for changes to the shared
memory storage allocation. (“1” means validate once per second, but only
once per request. “0” means always validate)

If you’d like to improve PHP performance even more with OPcache, try applying some of all of the below changes to your php.ini or opcache.ini config file. Or hire me.  (Performance gains are most noticeable on higher throughput servers):
