I forgot to mention that with mirrored swap, the mirrored *write* penalty
exceeds the *read* parallelization gains by RAID-1.

RAID-1 parallelizes only the read operations, while write ops are still
duplicated. With a swap bound system, your swap-write I/O doubles with mirrored
swap, choking both drives. Whereas with distributed (separate) swap partitions
you get a smooth swap-write distribution.
