    Smells like caching on the HP…

    You could only compare those results, if you'd stuff your LSIs into the
    HP as well. A magnitude is quite a lot in that regard. Then, what does
    this benchmark actually do? How much of it is CPU bound and how much is
    I/O bound? And I know, that the SmartArray often times has quite an
    amount of RAM cache on board, especially, if you buy one those bigger
    boxes, like a 380.

    Cheers,
    Stephan
