From C#, is it possible to detect the number of context switches that occurred while executing a block of code on a particular thread? Ideally, I’d like to know how many times and what CPU my thread code was scheduled on.
I know I can use tools like Event Tracing for Windows and the associated viewers, but this seemed a bit complicated to get the data I wanted.
Also, tools like Process Explorer make it too hard to tell how many switches occurred as a result of a specific block of code.
Background: I’m trying to test the actual performance of a low level lock primitive in .NET (as a result of some comments on a recent blog post I made.
It looks like procexp might be using the kernel thread (KTHREAD) or executive thread (ETHREAD) data structures that have a ContextSwitches field on them. It might be possible to get this from managed code.
