Related question: I started playing with mod_pagespeed when it first came out, however at the time it was very buggy and broke RichFaces based apps, PHP Gallery, and a few WordPress plugins that sites I host run, so I had to ditch it. That was ages ago though. Has anyone been running a recent version of it? What is your feedback?
