When using Instruments to capture FIXED_CYCLES and FIXED_INSTRUCTIONS on both an M1 based MacBook and also on an iPhone, the value of these counts is much higher when enabling High Frequency Sampling.
Why is the count of Instructions and Cycles higher with Higher Frequency Sampling?
Is it due to stack sampling overheads?
Which is more accurate to capture FIXED_CYCLES and FIXED_INSTRUCTIONS counts - with High Frequency Sampling or without?
