PageSpeed ​​Module
Mod_pagespeed is an open-source Apache HTTP Server or Nginx webservers module, which automatically applies selected filters to related pages and assets, such as stylesheets, JavaScript, and HTML files, as well as to image and cache requirements of websites. The biggest advantage of this module is that it does not require modifications to existing content or workflows, which means that all internal optimizations and changes to the file are created on the server side, presenting files that are changed directly to the user. Each of the 40 filters matches one of Google's best practices rules for web performance.
Because the PageSpeed ​​module is an open source library, updated frequently by developers from around the world and can be used by any site, hosting provider, or CDN.
Installation is relatively easy and can be done in two ways: from packages or build from sources on the following supported platforms:
- CentOS/Fedora, both 32-bit and 64-bit
- Debian/Ubuntu, both 32-bit and 64-bit
