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?). > what is the advise for a fileserver ? > (both running hardware raid5 (3ware) and software raid5 (on promise > controllers) A follow-up question: Does sw-raid5 checksumming use multiple CPUs in any way? /Martin
