I've been comparing zfs send and receive to cp, cpio etc.. for a customer data
migration
and have found send and receive to be twice as slow as cp or cpio.
Im migrating zfs data from one array to a temporary array on the same server,
its 2.3TB in total, and was looking for the fastest way to do

Did you run sync after the cp/cpio finished to ensure the data really is
on disk ? cp and cpio do not do
Im measuring time by using the time command in the command arguments
ie: time cp * / etc..
for copy i just used time cp pool/fs1/* /newpool/fs1 etc...
for cpio i used, time find /pool/fs1 |cpio -pdmv /newpool/fs1
for zfs i ran a snapshot fist then, time zfs -R send snapshot| zfs receive -F
-d
