WSL performance problems were mostly due to slow I/O. How does virtualization fix that?

  Translating syscalls to the NT kernel is slower than running Linux with a virtual filesystem.

    But in the end, the virtual filesystem is backed up by done Windows storage?

      Idk, but Microsoft cites these differences for the performance improvement. Maybe things can be speed up/cached when you are one-to-mapping the syscalls to NT kernel.
