A follow-up question: Does sw-raid5 checksumming use multiple CPUs in any
way?
It could if separate threads were submitting requests on the same
array, but I don't think it would be very likely. Lots of the
checksumming is done by raid5d which is single threaded.
Ofcourse if you had 2 raid5 arrays, they could quite possibly use one
cpu each.
