Benchmarking and Profiling

There are a few tasks that require you to either benchmark Python (by measuring its speed) or profile some Python source code (to figure out where code is taking too long).

Benchmarking Python

You should use pybench, under Tools/pybench/README in the Python source tree, for information on how to benchmark the Python distribution.

Profiling

Profiling seeks to measure the amount of time spent in various parts of the code. Here's a high-level overview of some of the tools available for profiling. We suggest starting with cProfile, which is the officially supported Python profiler.

We know the profiling documentation is confusing; please go ahead and ask us questions if you run into trouble!
