The old "you need 2x RAM for swap" rule is hard to forget.
I never really understood the rationale for that rule. It seems like a system with more RAM would need less swap, not more. In particular, it always seemed to me like it'd be a bit silly to use 8 gigs of disk for swap on a system with 4 gigs of RAM. Can someone explain the reasons for the 2x rule? Is there a performance boost?
