There is a thread quite similar to this but it did not provide a clear answer
to the question which was worded a bit odd..
I have a Thumper and am trying to determine, for performance, which is the best
ZFS configuration of the two shown below. Any issues other than performance
that anyone may see to steer me in one direction or another would be helpful as
well. Thanks.
ZFS Config 1:
zpool status
pool: rpool
state: ONLINE
scrub: none requested
config:

In a nutshell, for performance reasons, is it better to have multiple raidz
vdevs in the pool or just one raidz vdev. The number of disks used is the same
in either case.
Thanks again.
