PyPy had a longstanding issue :
ZipFile.extractall is very slow compared to CPython 2.6

https://bitbucket.org/pypy/pypy/issues/905/zipfileextractall-is-very-slow-compared-to

which has been fixed in the PyPy code base. The changes were entirely in zipfile.py (see the attached patch for PyPy)

The patch fixed a significant performance bottleneck in PyPy.

This is the same as issue30468. It isn't worth to open separate issues for different versions.
