[Chromium-dev] Some profiling info

[Mike H. <mho...@gr...>]

I've just started playing with this thanks to Alan, so bare with me.

It seems that the hangup is on the appside in libcrutil, 87% of the time 
spent there.  Does anyone know how I can get the function breakdown from 
within the libs?  optstack doesn't seem to be doing the right thing for 
me...  I've also set the kernel image to the correct place, but I still 
get a listing for no-vmlinux.

 From the crserver:

CPU: P4 / Xeon, speed 2399.55 MHz (estimated)
Counted GLOBAL_POWER_EVENTS events (time during which processor is not 
stopped)
with a unit mask of 0x01 (count cycles when processor is active) count
