Something i've been meaning to ask....
I'm transfering some data from my older server to my newer one. the
older server has a socket 775 intel Q9550 8 gb ddr2 800 20 1TB drives
in raidz2 (3 vdevs, 2 with 7 drives one with 6) connected to 3
AOC-SAT2-MV8 cards spread as evenly across them as i could
The new server is socket g34 based with the opteron 6128 8 core cpu
with 16 gb ddr3 1333 ECC ram with 10 2TB drives (so far) in a single
raidz2 vdev connected to 3 LSI SAS3081E-R cards (flashed with IT
firmware)
I'm sure this is due to something i don't understand, but durring zfs
send/recv from the old server to the new server (3 send/recv streams)
I'm noticing the loadavg on the old server is muuuuuch less than the
new one....
this is form top on the old server:
load averages: 1.58, 1.57, 1.37; up 5+05:13:17
04:52:42
and this is the newer server
load averages: 6.20, 5.98, 5.30; up 1+05:03:02
18:49:57
shouldn't the newer server have LESS load?
Do you have compression on? Compressing is more CPU intensive than
uncompressing.
