Apache module for faster web sites
As a complement to its Page Speed Firefox add-on, which measures website download and execution times, Google has released the mod_pagespeed Apache module. This is able to take a range of steps, depending on the configuration used, to optimise web sites before they are sent to the browser.
This includes inserting short CSS and JavaScript files into the HTML page and conversely exporting large style sheets and code segments into separate files. Other functions involve caching, minimising JavaScript and CSS and adding height and width information to img
elements. There is a web site which explains the individual filters and shows how they work.
Binaries of the module, which only run on Apache web server 2.2, are available for Ubuntu / Debian and CentOS. The source code should also be able to be compiled and installed under Ubuntu 8.04 LTS "Hardy Heron" and 10.04 LTS "Lucid Lynx", CentOS 5.4 and "elsewhere". However, it did not work in quick tests with Debian / Lenny.
