What you have to do is first load the kernel module sysprof-module.ko, then run the application:
# modprobe sysprof-module
It's a GTK2 app. You will see a button labeled "Start", click that, the app will then proceed to take samples. Click the "Profile" to stop. What you get is a breakdown of how CPU time is used on a per-file basis.
I used this for the first time yesterday, as I was trying to find out why a script was running slowly. My next post will explain more about the slow script. System Profiler showed something odd, but I could not pin down the cause of the slowness.
