PageSpeed Module is an open-source module for Apache and Nginx created by Google to help Make the Web Faster by rewriting web pages to reduce latency and bandwidth.
The plugin allows purge caches created by Apache or Nginx Module and turn on development mode for WordPress site, bypassing PageSpeed cache.
The plugin requires PageSpeed Module to be installed with your Apache or Nginx web server. If PageSpeed Module is not installed, the plugin does nothing.
