Can you try PyPy as well?

Apparently not :( (These benchmarks were done on an M1 MacBook Pro)

    $ brew install pypy3
    pypy3: The x86_64 architecture is required for this software.
$ brew install pyenv

$ pyenv install pypy3.9-7.3.9

I like using PyEnv for managing my Python versions. It will natively compile Python builds and should be doing the same on M1 (which is what I'm using). `pyenv install --list` shows you what is available.

EDIT: Not sure why they don't have newer versions of PyPy there (I don't use PyPy) but all it takes is a PR to here: https://github.com/pyenv/pyenv
