I set this up on the Alpha release and the results are below. I'm

55.99% gnome-shell perf-6425.map [.] 0x19b99e
This is how perf reports the dynamically generated code emitted by llvm.
But...
4.91% gnome-shell swrast_dri.so [.]
lp_tile_b8g8r8x8_unorm_swizzle_4ub
3.50% gnome-shell swrast_dri.so [.]
lp_tile_b8g8r8x8_unorm_unswizzle_4ub
2.60% gnome-shell libX11.so.6.3.0 [.] _XPutPixel32
2.57% gnome-shell libX11.so.6.3.0 [.] _XGetPixel32
That the percentages fall off so quickly is a little suspicious. To me
that reads as though gnome-shell itself is being starved for work to do
and that other things are actually taking more time. Is this perf trace
from the whole system or just of gnome-shell?

I used 'perf record -p 6425' to attach gnome-shell, so that's all it
should be. FYI - This is F17-Alpha-i686-Live-Desktop installed to a USB
HDD on the i845G box.
