Long Baking Lights process time on macOS and Linux

If you compare baking lights process on Windows vs macOS using the same test project, The input data looks the same for baking, But it's faster on Windows.
Although you can find a few calculations which take a shorter time on macOS, but the main process (texels) run faster on Windows.
During the test, I checked the performance on both OSs, One of the differences between them was the number of working threads. It was 37 active threads on windows (16 logical cores), while it was 16 active threads on macOS.

These baking calculations are handled in QSSGLightmapper which is a part of QtQuick3D project.
