PageSpeed modules & tools
Apache PageSpeed (incubating) is a technology that was born at Google, designed to help a website's performance optimizations. Faster websites offer a better user experience, boost rankings in Google and increase conversion rates.
Web server modules & plugins
Instead of manually improving your website you can let PageSpeed automatically do the optimizations for you. We-Amp offers a commercial PageSpeed module for Microsoft IIS and an open-source PageSpeed plugin for Traffic Server.
