How to detect hot locks !

[Neo]

Hi Guys,
Is there any way or tool exists which tells "hot" critical sections
in your code?

Just to add to this. I am using a third party library where I suspect
of having this kind of bottle neck.

Yes, you can observe contention count of critical section objects.
See this article for more details:

"Break Free of Code Deadlocks in Critical Sections Under Windows"

Also, this article demonstrates debugging technique how to locate
"hot spots". The article is about .NET application, but they use
WinDbg to debug native threads.

We use Memory Validator for leak detection and it has
some profiling that shows hot spots as well.

They have some other profilers etc. Good support and
decent price.
