It's usually pretty\nstraightforward for developers and webmasters to implement these suggestions by updating their\nweb server configuration, HTML, JavaScript, CSS and images. But we thought we could make it even\neasier---ideally these optimizations should happen with minimal developer and webmaster\neffort.\n\n\nSo today, we're introducing a module for the Apache HTTP Server called\n[`mod_pagespeed`](/speed/pagespeed/module)\nto perform many speed optimizations automatically. We're starting with more than 15 on-the-fly\noptimizations that address various aspects of web performance, including optimizing caching,\nminimizing client-server round trips and minimizing payload size. We've seen mod_pagespeed reduce\npage load times by up to 50% (an average across a rough sample of sites we tried)---in other\nwords, essentially speeding up websites by about 2x, and sometimes even faster. \n\n\nHere are a few simple optimizations that are a pain to do manually, but that\n`mod_pagespeed` excels at:\n\n- Making changes to the pages built by the Content Management Systems (CMS) with no need to make changes to the CMS itself,\n- Recompressing an image when its HTML context changes to serve only the bytes required (typically tedious to optimize manually), and\n- Extending the cache lifetime of the logo and images of your website to a year, while still allowing you to update these at any time.\n\n\nWe're working with\n[Go Daddy](https://www.godaddy.com/)\nto get `mod_pagespeed` running for many of its 8.5 million customers. Warren Adelman,\nPresident and COO of Go Daddy, says:\n\u003e Go Daddy is continually looking for ways to provide our customers the best user experience possible. That's the reason we partnered with Google on the 'Make the Web Faster' initiative. Go Daddy engineers are seeing a dramatic decrease in load times of customers' websites using `mod_pagespeed` and other technologies provided. We hope to provide the technology to our customers soon - not only for their benefit, but for their website visitors as well.\n\n\nWe're also working with\n[Cotendo](https://www.cotendo.com/)\nto integrate the core engine of `mod_pagespeed` as part of their Content Delivery\nNetwork (CDN) service.\n\n\n`mod_pagespeed` integrates as a module for the Apache HTTP Server, and we've released\nit as open-source for Apache for many Linux distributions. Download\n[mod_pagespeed](/speed/pagespeed/module)\nfor your platform and let us know what you think on the project's\n[mailing list](https://groups.google.com/group/mod-pagespeed-discuss).\nWe hope to work with the hosting, developer and webmaster community to improve\n`mod_pagespeed` and make the web faster.\n\n\nPosted by\n[Richard Rabbat](https://plus.google.com/106992973003627941930/about),\nProduct Manager, 'Make the Web Faster' initiative"]]
