@ben to be fair it's probably ZFS doing a lot of the heavy lifting here, but @stefano 's testing has shown that even on ZFS on proxmox (KVM) the performance still isn't quite as good as ZFS on FreeBSD (bhyve) - which is likely due to the ZFS modules in FreeBSD being native over additional kernel modules in proxmox (or any other Linux distro that can use it)

bhyve is definitely worth looking into if you use VMs though, for sure!

@paul @ben @stefano I don’t know, I could equally imagine the Qemu I/O paths not being ideal. Qemu is a beast of a code base, which even after years of effort hasn’t managed to get close to eliminating the big Qemu lock (BQL) for example; bhyve is tiny in comparison.
