When I launch the Xamarin profiler, there is a setting for Sampling mode which has two options, CPU and Real. There is also one line description on what it is, (ie.) CPU for constant sampling and Real for more realistic sampling. I don't see any other documentation. Can anyone please explain it in detail? I find that the result captured in CPU mode is double the result captured in Real mode (used sample app provided in Xamarin profiler documentation). Which one should I use for profiling my application?
