So today, we’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.
Here are a few simple optimizations that are a pain to do manually, but that mod_pagespeed excels at:
