Your problem might just be the choice of using a Dell RAID controller.
I have a 1 year old box connected to a 14 disk powervault (PowerEdge
2650) and it is dog slow compared to a dual opteron with 8 disks that
is replacing it.  It is all I/O for me, and the dell's just are not
known for speedy I/O.

But that is relative I would think.  Is the Dell RAID much faster than my desktop SATA drive with no RAID? I'm by any means as knowledgeable about I/O setup as many of you are but my 2 cents wonders if the Dell RAID is really that much slower than a competitively priced/speced alternative?  Would Joel's problems just fade away if he wasn't using a Dell RAID?
