Hey, I have a couple of short questions about my FreeNAS box.
I went back to the basics to purely test the performance of the disks, not utilizing zil or cache's yet, and I noticed something off, for some reason, when I make a pool of 4 (2x2) 1terabyte disks, and start doing random writes, I noticed that all 4 disks only do about 30-40 IOPS each, as opposed to about 70 I expected. Is this because they are mirrored and only get to about 70 combined? or should they be able to reach their 70 IOPS individually?
Also, I see there's always just 1 operation in queue for the disks at any given time, I figured I could increase this using the tunables zfs_vdev_min(max)_pending, but these seem to be deprecated in the latest FreeNAS version, is this true? My last question is if it might be possible to increase the amount of nfs daemons.
Thanks in advance!
