It's taken about 15 hours to copy 800GB. I'm sure there's some tuning I
can do.
The system is now running:

Try piping zfs data through mbuffer (misc/mbuffer in ports). I've
found that it does help a lot to smooth out data flow and increase
send/receive throughput even when send/receive happens on the same
host. Run it with a buffer large enough to accommodate few seconds
worth of write throughput for your target disks.
Thanks. I just installed it. I'll use it next time. I don't want to
interrupt this one. I'd like to see how long it takes. Then compare.
Here's an example:

That looks really good. Thank you.
