I just wanted to add that when I create a pool it is using ashift 9. Arent all
ssds 4k drives at this point?

sorry I have not, that is the next logical step but only my esxi servers have
10g interfaces and I cannot take them down at the moment.
I have been looking this issue up online and I do find some people with poor
reads and good writes. In some cases they are saying it was a mismatch in the

The cable is somewhat ruled out because I am seeing the same exact performance

Have you tried a native OI

Yes jim I actually used something similar to enable the 9000 mtu that's why I
want familiar with the config file method.
dladm set-linkprop -p mtu=9000 InterfaceName

am going to try enabling flow control first and i

If you're on OpenIndiana (well, you're on the list, but I think I
haven't seen a statement of your OS version), you can try "dladm

Flow control is a feature of the NIC and any two NICs can negotiate to
have it turned on, you don't need a switch in between. See
/kern
I am not sure that I can disable flow control since no switch is present. Is it
turned on in the host by default?

Second that.
The 9k MTU might also be hitting some NIC driver bug

Second that.
The 9k MTU might also be hitting some NIC driver bugs - non-standard
settings can, at times. Since the difference is only in the storage -

Always be sure to do your performance testing on the machine itself
first, before going on to test through more layers of the stack (i.e.
iSCSI). What does "iostat -xn 1" report
As a technical terminology nit - all components in a zfs pool
are "vdevs", albeit of different levels. "Leaf vdevs" (disks,
slices, files) are aggregated into top-level vdevs (singular,
mirrors, raidzN) and a pool is striped over them.
All in all, if the different vdev topologies yield the same

Hi I am trying to track down a performance issue with my setup.
I have 24 ssds in 6 vdevs (4 drives per) that are then striped. Essentially a

switched to a perch h710 and have each drive in raid 0 and presented to the os
