How big should swap be?

I saw this article, it is interesting. It says what I have long wondered myself, that having a swap double the size of your RAM is a hell of a lot!

this is much debated. Whats best is what you need for your system, who knows better then you? Google my friend. I have 2gigs of memory and only 1gig of swap. I hardly ever see more then 50Mb of swap space used.

Part of the reason for swap is it is needed for the computer to hibernate. If you do not hibernate then I have found that with 4GB RAM I never touch swap with what I do. If you run multiple VM's or crunch a lot of data you very well could.

Think about this though, with today's drive space, what is 4-5GB to most people? Better safe than sorry and you will never miss this. I set my swaps to 4GB just because on all my computers except my big rig desktop, which does not run a swap. Never had any problems either way.
