ZFS send/receive
Aug. 19th, 2015 20:26It's strange, but for this particular case
from-host > zfs send zvolume@snapshot-version|ssh to-host zfs receive zvolume
is faster than
to-host > nc -l -p port|zfs receive zvolume
from-host > zfs send zvolume@snapshot-version | nc -l to-host -p port
approximately by 16%.
Both hosts have a lot of free memory (~30 and ~60 GBs respectively), CPU load is about 0.3% at one core, both are located in same DC and share 500 MBps bandwidth.
Also, both are same OS version - joyent_20150709T171818Z
