After having used the built-in tracing profiler cProfile for a while now, I came across the statistical (sampling) profiler pyinstrument.

A statistical profiler does not influence the runtime of the program as much as a tracing profiler as cProfile does. Additionally, pyinstrument shows the result in a different way from cProfile.

So in this article, I will be profiling my repotool program. This program helps me maintain a mirror of FreeBSD packages that I use.
