Third party profilers

[jzoller]

I have an upcoming project where I'll be processing quite a bit of data coming over a serial port or USB. The timing budget for the processing is of the "faster is better" variety, and I'm looking for something that will allow me to accurately measure usage and timing in different threads.

My experiences with the built in LV profiler haven't been entirely wonderful, and tight LV integration isn't immensely important for this project. Does anyone have any experiences they can share about using third party profilers with LV? (For instance, any idea what NI uses?)

This is under Windows XP (RT isn't an option right now), likely with several dlls and the .NET framework involved.

Thanks,

Joe Z.
