PageSpeed automatic is a technology that was initially developed by Google, designed to help a website's performance optimizations. The project is now maintained by the open source community and resides in the Apache Incubator. Faster websites offer a better user experience, boost rankings in Google and increase conversion rates.
Pagespeed lets you measure and (automatically) optimize your web pages and comply with web performance best practices. Speed up your web site and boost web performance!
Pagespeed server modules
Instead of manually improving your website you can let PageSpeed automatically do the optimizations for you. Google offers open-source modules for Apache and NGINX, We-Amp offers an open-source plugin for Apache Traffic Server and a commercial module for Microsoft IIS.
