i would imagine that cpu has nothing to do with it and encryption
would add no overhead at all.  i would image that seeks dominate
your performance numbers.

i don't think coraid could manage with such performance.  this
morning's dump is not outlandish but it is a bit bigger than
normal — 1.65gb in 8k blocks.  note that this isn't a super
i/o rate because kenfs doesn't go full-tilt boogy on dumps
and because the backup worm is across town.  but still, 
it does manage to complete in under 12 minutes.
