I used https://github.com/python/pyperformance pyperformance to
compare Arch linux latest
Python 3.8.3 (default, May 17 2020, 18:15:42) [GCC 10.1.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
against a vanilla build (configure make makeinstall) of python 3.9b1
Python 3.9.0b1 (default, May 19 2020, 21:09:14) [GCC 10.1.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
I find all the bench marks seem to be slower in python 3.9b1.

Is this because I haven't built in the same way as Arch or are there
real slowdowns in this beta? Or even dumber have I got the results the
wrong way round?

Most builds of python included with distribution packages are built with
various levels of optimization. I have experienced slowdowns from source
built python of the same version as the distribution python even when
using some optimization flags with the configure script. This appears to
be normal behavior and is not cause for concern about the performance of
python 3.9.0b1
