If your concern is for performance, use raw swap, as there is a performance hit with RAID, because you have to write every page twice. It usually does the writes in parallel, and you shouldn't notice a big decrease, but the possibility is there. -- Paul <http://paulgear.webhop.net> -- Everyone who voted for slavery was free.
