What platform are you profiling on?
a pII 400, 128mb. I also have a pentium 233mmx laptop and a dual pIII 500 box at work I can run tests on. When I get back from my 3 week leave I start Friday, I will install linux on my ppc 604e, perhaps on a bebox I have at work also. Then I will try and run tests on ppc as well. Dunno how hard getting sound to work will be.
