OPcache. Best configuration for 10+ websites

I published post about my PHP 7 installation. There no need Alternative PHP Cache (APC) anymore because there has very good PHP accelerator OPcache. Moreover APC doesn’t compatible with PHP 5.5 and older. By the way, if you are first time heard about OPcache, then:

OPcache 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. PHP.net

PHP.net

I have more than 10 websites on my server. And today I would love to share my OPcache. Best configuration for 10+ websites configuration. In my opinion and my experience there is best configuration.

First of all I want show you how’s it works. I didn’t restart server for few days.

And now I’m sharing my OPcache configuration
