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.

Significant (t=-96.22)

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?
