mod_pagespeed is the latest addition to our family of products, performing on-the-fly optimization in the Apache™ 2 HTTP Server. It provides webmasters and web developers that manage their Apache 2 configuration with technology that applies Page Speed performance best practices automatically. Webmasters can get the benefits of the optimizations without having to manually going back and fixing the performance issues that Page Speed detects.
This solution is valid if you do not want to carefully optimize your site, and it come for now at huge initial CPU costs till the cache is filled up. The load on my server has proven to be unacceptable (for me) and I was forced to switch it off. But it may work on your server depending on the page size, number of visitors. Authors are working hard and communicating a lot on the official mailing list to reduce that load and improve the code in the coming weeks
If you trust me, you can download the library module libmod_pagespeed.so for Apache 2.2
# This page lets you view statistics about the mod_pagespeed module.
# You may insert other "Allow from" lines to add hosts you want to
# allow to look at generated statistics. Another possibility is
# to comment out the "Order" and "Allow" options from the config
# file, to allow any client that can reach your server to examine
# statistics. This might be appropriate in an experimental setup or
# if the Apache server is protected by a reverse proxy that will
# filter URLs in some fashion.
Allow from localhost
You may be forced to remove mod_deflate
You can disable mod_pagespeed by adding in the url ?mod_page_speed=0

I was receiving some strange errors (HTTP error 501) while committing to my public subversion (http://svn.waltercedric.com), all my problems were related to mod security This error 501 means most of the time that the client changed authentication halfway through the commit. That is, it started the commit by sending http requests with a Basic auth header of user1, and then a few requests later it sent a Basic auth header with a different user. Yes but.. …
