This is on the mark.

But there's another issue which is what cripples windows for dev! NTFS has a terrible design flaw which is the fact that small files, under 640 bytes, are stored in the MFT. The MFT ends up having serious lock contention so lots of small file changes are slow. This screws up anything Unixy and git horribly.

WSL1 was built on top of that problem which was one of the many reasons it was slow as molasses.

Also why ReFS and "dev drive" exist...
