I'm very sceptical that a fileserver would gain any performance from HT.

In fact, I don't really realize why you even need two CPU's? If you are
doing database lookups it's another thing though, also HT could give a
performance gain in that case (if it's supported by the linux kernel?).

A follow-up question: Does sw-raid5 checksumming use multiple CPUs in any
way?
