So having 4 pools isn't a recommended config - i would destroy those 4
pools and just create 1 RAID-0 pool:
#zpool create sfsrocks c4t001738010140000Bd0 c4t001738010140000Cd0
c4t001738010140001Cd0 c4t0017380101400012d0
each of those devices is a 64GB lun, right?
I did it - created one pool, 4*64GB size, and running the benchmark now.
I'll update you on results, but one pool is definitely not what I need.
My target is - SunCluster with HA ZFS where I need 2 or 4 pools per node.

ah, you were limiting the # of dnlc entries... so you're still seeing
ZFS max out at 2000 ops/s? Let us know what happends when you switch to
1 pool.
I'd say "increasing" instead of "limiting".
