If you are a Python developer like me, you probably know the profile and cProfile modules that provides deterministic profiling of Python programs.

These modules are awesome – however, when it comes to analysing the data to improve your program, the provided pstats module is generally not powerful enough if you have quite a large codebase.

And here graphical tools comes in handy! I tried RunSnakeRun, and this is a really great program that allows you to analyse the profiling data under multiple angles (a nice view is by file), so you can find easily the bottlenecks and fix them.

RunSnakeRun helped me to improve the “mach help” command. It is a cross platform tool. Note that if you are on GNU/Linux and that you have the KDE desktop (or don’t mind to install the required KDE dependencies), KCacheGrind can be used with Python also.
