Windows 10 WSL CPU Scaling Performance vs. Linux
Written by Michael Larabel in Operating Systems on 1 August 2017. Page 4 of 4. 17 Comments

While in pure CPU tests that are well threaded, Ubuntu on Windows 10 WSL was keeping in line with the native Linux installations.

We haven't seen any situations where using Windows 10 WSL is leading to better scaling than Linux.

Little to no scaling with PostgreSQL on Windows 10 WSL due to the poor I/O performance.

Well, that's where things stand today with Windows 10 WSL running Ubuntu compared to native Linux distributions. The performance overall tends to still be in line with the results when running Linux bare metal on the same hardware, but the slow I/O performance is the big difference and there are also other select cases where WSL wasn't performing quite as good. But still it's an interesting environment for testing and makes for fun experiments with Ubuntu/Fedora/openSUSE now being accessible from the Windows Store. Those different Linux distributions compared on WSL are being compared for an upcoming article on Phoronix.
