Windows 10 WSL vs. Linux Performance For Early 2018
The Windows WSL performance was competitive on Ubuntu and openSUSE for the AOBench ambient occlusion renderer, while VirtualBox was much slower. The highly-tuned Clear Linux out-of-the-box was delivering significantly faster performance for this benchmark.
With the LAME MP3 encoding benchmark there isn't a whole lot difference between the different platforms except for when testing Clear Linux with its much faster out-of-the-box performance.
WSL was running faster than Docker and VirtualBox for FFmpeg video encoding.
