For more complete information about compiler optimizations, see our Optimization Notice.

You have options to increase the sampling rate (probably with some influence on performance). My experience may not be relevant, but I suspect you will need run times of at least 10 seconds with each function you want to profile totalling at least 5%, to get useful results.

Hello ,

Till I know you can get to a minimum of 1ms sample rate. Also, it is suggested to run your critical function in a loop to get a larger execution time and then do sampling.

Direct link to the same problem.


Time resolution of VTune is around 3ms.
