At the risk of making an arse of myself again...

I think the logic was that if you needed more than (X x RAM) swap space,
the machine was going to be unusably slow anyway, and performance
wouldn't improve by having any more swap available. Values for X
probably vary widely, but I've always been told the value of 2. Disk
space wasn't always as cheap as it is now, so this rule of thumb was a
way of not dedicating too much of an expensive resource to a single use.

With memory prices the way they are these days, you can probably afford a
desktop machine that doesn't *need* any swap at all.
