ZFS is optimized for fast bulk data storage and data integrity and not so much for transactions. It seems that adding a non-volatile hardware cache device can help quite a lot, but you may need to use OpenSolaris to fully take advantage of it. It is important to consider how fast things will be a month or two from now so it may be necessary to run the benchmark for quite some time in order to see how performance degrades. The 3079 IOPS is probably the limit of what your current hardware can do with ZFS. I see a bit over 3100 here for random synchronous writers using 12 disks (arranged as six mirror pairs) and 8 writers.
