I am setting up a Linux server (probably will be NixOS) where my VM disk files will be stored on top of an NTFS partition. (Yes I know NTFS sucks but it has to be this way.)

I am asking which guest filesystem will have the best performance for a very mixed workload. If I had access to the extra features of BTRFS or ZFS I would use them but I have no idea how CoW interacts with NTFS; that is why I am asking here.

Also I would like some NTFS performance tuning pointers.

    Don’t do ZFS on ZFS. It will destroy performance.

    I personally go for EXT4 as is solid and light weight. It is also somewhat resistant to power loss

      That’s what I said. Cow on top of cow is bad. Pretty sure ext4 isn’t on option on opnsense. UFS or zfs. Which is the only reason I mentioned it at all when presented with that choice.
