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
