Google feels the need for speed. This is why the company started developing mod_pagespeed all the way back in 2010. This open-source Apache module tries to take some of the difficulty in optimizing webpages away by automatically doing it for web developers and webmasters.
Fast forward two years and eighteen releases and you'll find us here today with Google officially stripping the Beta tag from the module. Google is promising their commitment to continue working with the open-source to continue developing this really cool module which is already used by over 120,000 sites.
According to Google, "the product is used worldwide by individual sites, and is also offered by hosting providers, such as DreamHost, Go Daddy and content delivery networks like EdgeCast." Moving out of Beta should help the module pick up users and generally speed up the web around you.
Quick websites make all the difference for the end-user, and this is one of the main reasons we switched our servers over to something a bit quicker. If you're interested in the technical side of mod_pagespeed, Google has provided the following video to quench your thirst for knowledge:
