    9pfs? That's cool, but only if it was available on Windows so I could see my ext4 and Btrfs drives on Windows (don't want to mess around with Ext2fsd/WinBtrfs)...

      This improved performance makes it more desirable, so there will be more impetus.

      Windows host support for 9pfs export to guests V2 patch will be merged "soon".

      There's a 32-bit Windows guest 9pfs driver here.

      I've used sshfs for Windows guest to mount Linux host fs where high performance isn't important.

      On WinXP I even used Samba. <Shudder/>.

          How does 9pfs compare to virtiofs ? It even seems to have a windows driver.

            Isn't WSL2 using 9p? Can't that be used?

              I use virtiofs. It is much more performant than 9p. At least until now.

                Could you share your virtiofs configuration for Windows guests (if I understood you correctly and that’s indeed your configuration)? In my experience, virtiofs on Windows was such a clusterfuck from both performance and stability POV that I just ended up using a tuned Samba.

                  Not gonna lie, I was somewhat taken aback by what I initially read as a "massive 9fps improvement" with AVX. đŸ˜¸

                    Sorry, I mean I use it with Linux guests. I have not yet tested with Windows. Samba is what I use with Windows, which is OK. The issues with samba is that Linux does extra file caching, and with virtiofs you can disable this.
