An easy demo of the performance problem is to compare the execution speed of the single command: >>> help('modules') in a python3 shell in a terminal window (it's real fast), vs. inside the IDLE3 shell (it's terribly slow). I understand that IDLE3 uses the tkinter.py/Tcl/Tk toolset for windowing. There's something slowing it down on the M1 Mac Mini (MacOS 11.2.3), making it run much slower than on a Wintel PC or Linux Raspberry Pi. I don't know if the problem occurs with any Python versions other than 3.9.2 on MacOS.
