[Scons-users] SCons very slow on GitHub actions

[Leonard de Ruijter]

Yes, I tried that option but it doesn't give extra insight unfortunately.

I just tried the windows-2019 image and it is way faster. 10 seconds 
total script reading time, compared to 70 seconds on 2022 and 2025. The 
2019 image only has Visual Studio 2019 installed.

Python version (e.g. 3.13) is still slow on 2022/2025 images.
