Beefy 9.2.x box not performing as expected... ESXi 5.5 host

This is my first post on the forums and I've read countless hours for several weeks, and tried so many settings that I'm finally going to ask for help because I just can't seem to get an expected result from this box.

Hardware setup:
Supermicro X9SRH-7TF w/X540 Intel 10GB NICs
Xeon E5-1650 v2 3.5Ghz Hyperthreaded 6-core CPU
HBA LSI2308 based (using "mps" driver)
128 GB of RAM

There are 18 drives in the machine. 10 SAS 2TB drives, 6 SSDs for a volume, and 2 SSDs for ZIL/SLOG.
