Scaling a site or app is a tricky topic to tackle. There’s no shortage of technologies out there to increase performance, spread load, distribute databases and so forth; the difficulty is choosing from the sheer volume of options and permutations.

As a user, how often have you thought “I wish this web service was faster.” As a CEO, how often have you said “just make it faster.” Or, more simply, “why is this damn thing so slow?”

Webmaster Level: All
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:

In early 2008, Wayne Shea and Tenni Theurer wrote a YUI Blog post on iPhone Cacheability in which they shared the results of research into various characteristics and limitations of Mobile Safari’s cache in iPhone OS 1.x. Among other things, they found that individual components larger than 25KB were not cached, and that there was a maximum total cache size of between 475KB and 500KB.

This is the second in a series of articles describing experiments conducted to learn more about optimizing web page performance. You may be wondering why you’re reading a performance article on the YUI Blog. It turns out that most of web page performance is affected by front-end engineering, that is, the user interface design and development.
