I guess I should try this with GHC7, but is there reason to believe it will perform better?

Yes -- there are huge GC and inlining improvements. In our (unreleased) new benchmarks, the Snap webserver is seeing 20-30% improvements out of the box. One thing you could try for 6.12 is turning parallel GC off -- we've found horrible scaling behaviour if you don't. The RTS flag for that is "-qg". G -- Gregory Collins <greg@gregorycollins.net>
