1. Profiling with pyinstrument

   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.

2. Profiling Python scripts (5): ent_without_numpy

   This is the fifth in a series of articles that covers analyzing and improving performance bottlenecks in Python scripts. The program ent_without_numpy.py is a lot slower than the version that uses numpy. The performance of ent_without_numpy.py is the topic of this article.
