WAIT_TIME

How exactly is WAIT_TIME determined under the callgraph collector? How accurate is it? Does it include time spent in kernel-space?

Can you take SELF_TIME - WAIT_TIME to get CPU time? When I do this for an application I am profiling, I get numbers that I don't quite beleive for __sigsuspend, nanosleep, and some others.

mathewmills ,

as far as I know the wait time is determined using some heuristics. so you can't count on these figures 100%.
