11 Not really. Think about live-CDs, the usually do not use swap space.
12 However, I heard that having at least a little swap space may increase
13 performance, regardless of how much free RAM there is. Don't know if this is
14 still true nowadays (if it ever was), I doubt it.

19 If you have enough RAM (with 4GB you probably have, but that depends on how
20 you use your workstation), you can even put your swap into RAM. Sounds
21 silly, but claims it makes some sense. I
22 don't believe it, but I'm no expert.
