3.10. Hardware profiling execution speed

Profiling does not have any effect on your application’s execution speed on hardware. Your application runs as normal.

However, downloading the image to the target can take a little longer than normal due to the enabling of profiling. In addition, the actual creation of the analysis report takes some time after the termination of the run. The amount of time required depends on varying factors, including the sampling rate and whether or not you have enabled program trace. The Backlog field in the live update view gives you a good indication of how much longer is needed for the ARM Profiler to create an analysis file.
