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?
I think it's just from 'the not-so-long-ago' days of yore when 128Mb went into your sig.txt as boast material, with nameless proprietary programmes that were resource hogs needing more than that. 2 times seemed to be the required measure and just carried over into other programmes.
