Benchmarking Ubuntu 18.04 On Windows Subsystem for Linux: WSL Leading Bare Linux In More Tests
In the Fhourstones test, WSL was actually faster than the bare metal Ubuntu 18.04 installation, due to better CPU frequency scaling on Windows or other optimizations.
The SciMark2 benchmark with Ubuntu 18.04 WSL was also faster than the native Ubuntu 18.04 installation.
While the x264 video encoding performance remained slightly lower with WSL.
The OpenMP-driven GraphicsMagick image resizing process also had some performance overhead with WSL.
The Stockfish chess engine was delivering roughly the same performance throughout.
