Windows 10 vs. Windows WSL vs. Linux - Ubuntu / openSUSE / Debian / Clear Linux
The 7-Zip compression performance was only lightly affected when running the three Linux distributions on WSL.
Also no real difference with the C-Ray ray-tracing performance when run under WSL.
The FLAC audio encoding performance was also basically the same except for openSUSE running slower, likely due to its older GCC4-based compiler stack.
With Libjpeg's tjbench, there were no real surprises either in the performance.
