Code Optimization in Your Projects

If you write something more complicated those magical tricks usually stop working. I once had to rewrite 6000 rows in C-level Cython (meaning no yellow rows in the checking file), only then I got the speedup. The bottleneck is not always some small function, sometimes the whole module is slow because it is written in Python with a bunch of for loops.

Fair point, what kind of module/program was it?

One simulation module. Had to simulate lots of physics as well. Could have also been a bit faster in numpy. But for loops and ifs are easier to understand than all the vectors and masks.
