When you have multi-disk systems an LVM swap can be faster than a
separate swap, it only has to extend through several disks. And even the
rest of the time, the ease of administration LVM brings justifies swap
LVM nowadays IMHO. Dedicated swap partitions are pretty much a PITA when
the hardware (disks) changes - either you systematically add a swap
partition to every single disk, or you pray the one your swap is on will
never be pulled from the box.
