[clug] to swap or not to swap that is the question

[Kim Holburn]

I have read several places that linux systems are always better with 
(HD) swap (suggestions were that swap allows the system to not run out 
of memory).  I don't understand this.

Suppose you have a system with say 1G of RAM and swap of 2G.  How is 
that better than say a system with 2G of RAM (or even 3G RAM).

Is it because HD is so much slower that the wait causes everything to 
slow down?

Help me out here - inquiring minds etc....
