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: https://github.com/ThomasWamm/TerraLunar.git All it does is 2-D orbital mechanics simulation, to teach me Python.
