I'm profiling part of my application using Visual Studio 2012, it's a dll containing native C++ and .net C++/CLI managed code. The performance report nicely shows information for all my managed code, but any place the managed code calls into native code, I can't dig down, only get [Unknown] shown as the location. I really need to profile the native code, that's where the bulk of the functionality lies.

  • That is very random, but in this case it actually worked Mike. Thanks. Not so applicable with a function utilizing only 0.1% CPU though. Question still valid. – Jeff McClintock Oct 17 '13 at 00:38
  • Glad it worked for you. I only worry about big stuff. Each thing I fix reduces the total time, which is the denominator in the fraction of time taken by other things. Do this several times, and what was originally 0.1% can ultimately become 10% or more. – Mike Dunlavey Oct 17 '13 at 13:52
