I find IO on windows is fine, the problem with WSL1 was that the standard windows model doesn't line up well with Linux (fairly fundamental things like in Linux you can delete open files, which you can't do in Windows).

You couldn't switch Windows to a more linux-like model, it would break all existing windows programs.

You can delete open files on Windows, but you need the right option (FILE_SHARE_DELETE).
