Firstly I have to say we haven't yet deployed it yet. I did dig into it to try and find if I could output some statistics on how much bandwidth the compression was saving, but I got lost and gave up ;-) We have a number of sites who don't have great connections and testing with them the improvement in speed of pages was big. Processor overhead isn't something I really have to worry about with the nunber of users on my system. We are defintely going to deploy it though.
There is a threshold parameter you set (compressionThreshold), which is the number of bytes (I think minimum is 128) - below which it doesn't compress, we currently have it set to 512 - so if your worried about processor overhead you can play with that so that its only larger pages which get compressed.
