> I really doubt that WSL2 will be at native speed with the Linux file system

I had the same doubts, but when I finally took the time to install it, I found out that I was wrong. One Java program that I use, which is very heavy on the filesystem and slow like hell under Windows it a LOT faster under WSL2.

As Java profiler support is poor on Windows, I now use WSL2 to run async-profiler sessions and get results as accurate as on native Linux.

EDIT to add: you really have to run things fully in the WSL2 filesystem, be it for compiling or using a program. The performance is awful if you run WSL2 processes under the Windows filesystem.
