A Look At The Intel Cascade Lake Performance For Windows Server 2019 vs. Linux vs. FreeBSD Benchmarks
The SciMark2 micro-benchmarks performed similarly on Windows Server 2019 to the Linux distributions except for Clear Linux that performs much faster thanks to its default compiler optimizations.
The x264 video encode performance on Windows Server 2019 was coming in just shy of FreeBSD 12 and Clear Linux while ahead of the other operating systems tested.
The OpenMP-threaded GraphicsMagick program for manipulating images saw roughly similar performance to FreeBSD 12 but behind the Linux distributions.
The Stockfish chess benchmark performed similarly to Linux/FreeBSD for the Stockfish chess engine except for being much slower on WSL.
Besides WSL having I/O bottlenecks, in the highly-threaded workloads with this Cascade Lake server on Windows Subsystem for Linux we are also seeing much lower performance than we normally do out of desktop/HEDT platforms.
