This plugin is based on https://github.com/rlerdorf/opcache-status which is for general PHP use, we have turned it into a WordPress plugin for ease of installation. Apart from some rearrangement of scripts to suit WP load conventions, the code is to date unaltered. WordPress capability ‘activate_plugins’ is required to see it in the admin menu and to run it.
After you install and activate this plugin, look in the admin Tools menu for OPCache.
