What profiling tools do you people use?
Optimize It (http://www.borland.com/optimizeit/)
That's what we use, I think the evaluation license allows you to 'test' the software for 10 days or so, giving you enough time to fix a memory leak :)
I've got some gtk-based profily plugin for Eclipse that works really well... however I only used it once, to find out where some crazy object leak was occuring, and it was so whacked out that it didn't actually help! (It was a resurrected resource in a finalizer - bloody difficult to find)
Mostly I just use -Xprof to find out what's going on if things are too slow.
