Actually, there IS some kind of RAID support built into the swapping code. If you activate 2 swap partitions with equal priority, all swapping will get distributed equally to those partitions - that might give some performance increase, of course!
(add parameter pri=xx to /etc/fstab swap entry.) HTH. Tino.
