[New-bugs-announce] [issue43511] Tk 8.6.11 slow on M1 Mac Mini MacOS Python 3.9.2 native ARM version

[Thomas Wamm]

New submission from Thomas Wamm <thomaswamm at gmail.com>:

Comparing performance of a Tkinter graphics program with Python 3.9.2 on an M1 Mac Mini, I find it to be slower than earlier versions, and much slower than the same program running on other computers such as a Raspberry Pi 3B (Python 3.7.3).

Initial investigation suggests the slow down is because of Tk 8.6.11.
The same program on Windows 10 on Intel i5-8250U is at least 10x faster, contrary to expectations.

Has anyone noticed similar?

The program is simple & portable, downloadable from:

All it does is 2-D orbital mechanics simulation, to teach me Python.
