Python Versions Performance

Question

Where I can find a comparative speed benchmark between python versions?

For example the performance between 2.6, 2.7, 3.0 , 3.1 and 3.2 versions.

Answer 1

The Python Software Foundation hosts a speed comparison site at https://speed.python.org/comparison/ that provides an overview of different benchmarks.

Currently, it only includes CPython versions (that are still supported) but PyPy has a similar site available at: https://speed.pypy.org/comparison/
