Looking for process profiling tool

[Quark Fusion]

I recently got a need to trace how actively a process calls to system functions like thread synchrotisation. I has tried AQtime and Intel VTune Perfomance Analyzer, but AQtime simply crash all the time and VTune can't attach to already running processes (or I just don't found that option).

Did you know about tools that can attach to a running process and count calls to various routines (taken from debug symbols, not source code)? And it must be Vista-x64 compatible.

windbg would be a place to start

Im actually don't want to digging into code, quick analysis of process behavior is what I looking for. (I suspect there is a bug in thread synchronisation.)

process explorer then can give you insight to what calls a process are making

What kinds of things would give you reason to trace such things? Consider xperf from the performance toolkit for this.

process explorer like tool shown that process have thread synchronization call last in his stack during high cpu consumption, so i want to count how much cpu time actually process spent calling that function, i suspect that most of that cpu time process check another's thread work instead of waiting for synchronization object.

I didn't figure out how to use xperf for this particular task. (Seems that i can do kernel profiling with it)

… After some research: is this what i looking for? Do i need LOADER flag? (I need to profile already running process)
