This module, with the \"Optimize for Bandwidth\" feature enabled, automatically optimizes pages, similar to Chrome's optimizing proxy. This solution benefits all browsers, secure sites, and desktop users, reducing outbound traffic. The module can be configured for more advanced optimizations like cache extension, inlining, lazyloading, and deferring JavaScript. PageSpeed is also open-source, and porting efforts are underway for other web servers.\n"]]
