Google’s been playing around with the Apache Web server, and they’ve announced a new module:
[W]e’re introducing a module for the Apache HTTP Server called mod_pagespeed to perform many speed optimizations automatically. We’re starting with more than 15 on-the-fly optimizations that address various aspects of web performance, including optimizing caching, minimizing client-server round trips and minimizing payload size. We’ve seen mod_pagespeed reduce page load times by up to 50% (an average across a rough sample of sites we tried) in other words, essentially speeding up websites by about 2x, and sometimes even faster.
Well, we’ll just see about that. I actually installed it last night, and about half the time it sped up the load time considerably, and the rest of the time it refused to load at all. I’m still testing on some smaller sites, but I’ve pulled it from here for now.
