Comment 26 for bug 81858

So, I've got the 'ati' driver in the config, but reading the man page for it, it looks like it loads one of radeon/r128/etc depending on what you have - so I believe it's running Radeon.

Just watching on top, the linuxactionshow.com page scrolling up and down shows most of the CPU is in Xorg; for the iPhone digg page I see it at ~100% on Xorg but then I see it bouncing to 100% on the firefox process for a while and back to Xorg.

What's the right way to profile this - I guess we could attack Xorg/firefox with gprof or oprofile; but is there anything higher level to see what is going on in firefox or what primitives the X server is taking its time on?
