> Native ntfs tools are much faster than Unix ones in some situations. The issue is that running Unix software on windows will naturally have a performance impact. You see the same thing in reverse using Wine on Linux.

Not true. There are increasingly more cases where Windows software, written with Windows in mind and only tested on Windows, performs better atop Wine.

Sure, there are interface incompatibilities that naturally create performance penalties, but a lot of stuff maps 1:1, and Windows was historically designed to support multiple user-space ABIs; Win32 calls are broken down into native kernel calls by kernel32, advapi32, etc., for example, similar to how libc works on Unix-like operating systems.

It's pretty typical these days for software, particularly games of the DX9-11 eras to perform better on Wine/Proton then they do under native Windows on the same hardware.
