[Speed] Analysis of a Python performance issue

[Victor Stinner]

Hi,

I'm happy because I just finished an article putting the most
important things that I learnt this year on the most silly issue with
Python performance: code placement.

https://haypo.github.io/analysis-python-performance-issue.html

I explain how to debug such issue and my attempt to fix it in CPython.

I hate code placement issues :-) I hate performance slowdowns caused
by random unrelated changes...
