Comment 50 for bug 416073

Looking at the profile of etracer on my GM45, there's not much we can do with this app --there may be a few percent to shave off total, but for the most part the cpu's being wasted on fixed function OpenGL handling. framerate with default config is reported between 30 and 60 fps (sadly, there doesn't appear to be a demo mode that would make etracer a reliable benchmark application) regardless of whether I run xcompmgr -a or not.

To track down a regression, we're going to need to bring up the two systems side by side with sysprof and top. Sadly, we won't be able to compare perf output between the two, which is the other key to performance debugging.
