I have it turned on for the forums.

I have it set at level 1 (default)

You can set it from level 1 -> level 9

But -- the compression level at level 9 makes the data sent smaller, however any time you save in sending the data is spent in the actual compression process. So you really are losing data sending time, and gaining it back in processing time and just adding a load to your processor.

Thats what I read on the vBulletin forums about mod_gzip, at least.
