Things are tested from inside a VM, that runs inside a Proxmox-VM, that runs on my Desktop (that performs pretty good, BTW :)) 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!
