I think zil_disable may actually make sense.
How about a zil comprised of two mirrored iSCSI vdevs formed from a
SSD on each box?
I would not have believed that this is a useful idea except that I
have seen "IOPS offload" to a server on the network work extremely
well. Latencies on gigabit ethernet are pretty small these days.
Yes, Gbe only adds about 100us to the latency and when using a raw SSD
as a backing store it should be a lot better than what the OP is doing
now (and he can use one of the less costly models).
