streaming isn't the issue, its the backup/restore time. It scrubbed 3306gb in 10h0m so ~92mb/s during a scrub if no other zfs activity, ~60mb/s read during a backup if no other activity, ~30mb/s read with 5mb/s torrent activity on another drive. Pretty dismal. 1080p blu ray is 25-50gb each 4k are 50-100gb, operations that took a few hours under hfs take a full day under o3x.
Same issue as this person is having:

so if you are running OS X on your Mac Pro as its operating system (bare metal) and running ZFS on top of that .. vt-d does not come into play and ZFS gets the storage devices at the hardware level..
and as brendon says.. a Mac Pro 3,1 is plenty good for a home filer, media server, etc.
Yes its plenty fast, but 6 o3x pools on one machine doesn't seem to work well. I reread your last post re: RDM, I guess that is enough for the ZFS VM.
Edit: I was thinking to try openzfs on ubuntu first since I won't have to recreate the pools. Or is there an openzfs vm? napp-it is oracle zfs correct? Would I need ubuntu server or just the desktop version? Would appreciate some general steps of how to connect the disks to ubuntu in vmware fusion via rdm and then serve the openzfs volumes back to the host. Thanks all for your help!
