One thing that might also affect your performance testing is that
FreeBSD disk I/O under KVM -- which is what Proxmox uses to run
FreeBSD -- has historically been pretty terrible, especially with ZFS.
The reasons for this are understood, I think, but last I heard the
author of the virtio block driver was time-constrained and hadn't had
a chance to work on it.

Thanks!
