    The benchmarks shouldn't be CPU bound in the case of the Supermicro. It has twice the # of processors of the HP but the HP has 8 cores total in the one processor (Xeon E5-2640 @ 2ghz). Postgres prefers higher CPU frequency rather than  number of cores. The Sunfire has 48 drives and so writes should be spread fairly evenly, reducing writes per drive. Is there any other information I can provide?

    Could you please provide a few more information about the servers? CPU speed, cores, RAM, etc?

    OmniOS tuned or all raw installations? All the same OmniOS version?
