I'm working on a performance counter, which will be always running inside the app, ever a release version. So, it needs to be as fast as possible.
I did compare c#'s StopWatch and c++ rdtsc(), and with 100 000 000 cycles taking 3 secs rdtsc() is a clear winner vs 23 seconds that StopWatch needs.
My problem is that I only know how to call rdtsc() from c++.
Can anyone suggest if there is a standard way to do it, or if I have to write a managed c++ dll?
