Just as a curiosity... does anyone have any guesses as to the runtime performance cost of hosting one or more swap files (which thanks to on demand creation and growth are presumably built of blocks scattered around the disk) versus having one or more simple contiguous swap partitions? I think it's probably a given that swap partitions are better; I'm just curious how much better they might actually be.
