HI.
I have been running iSCSI with the old iSCSI stack before 9.3 without an SLOG and have been fine ( because the writes were async ).
Now I set-up a new rig with 9.3 ( using CTL this time, of course ) and the write performance on my ex 5.5U2 datastore mounted over iSCSI via 1GBPS network ( mtu 9000 ) is showing 169 millisecond write performance and 6 millisecond read performance ( latency ).
Am i missing something ? does CTL do SYNC writes by default now instead of async? I think the high latency is messing with my backup appliance, thats why I'm asking :)
