The idea here is to add additional events through the execution in Python, I'm guessing. PyStart, PyResume, PyThro, Preyyield, PyN1, call. What this means is that running the program under the other other provider will make it slow. We are talking about tracing profilers. Other kind of profilers, sampling profilers, they work differently and they will not use these APIs. They trade accuracy for a lower impact. And therefore, these profiles are faster, but as you say, they trade kind of like accuracy for speed.
