This is incorrect. SWAP is used on a [1GB ram/2GB swap system].
I talked to Rik about this. He said generally SWAP is a good thing and increases performance.
However, in my case it does not.

Nov 22 12:18:44 <riel> war: it all depends on what you use the computer for Nov 22 12:18:56 <riel> war: that's a very important thing to specify ;) Nov 22 12:18:57 <war> General X apps, staroffice/netscape/media stuff(aviplay)/etc Nov 22 12:19:06 <war> compiling apps once and awhile Nov 22 12:19:13 <riel> war: ok, in that case you omost likely don't need swap Nov 22 12:19:32 <riel> war: but you really _need_ to tell what you are using the computer for before anybody can give a sensible answer ;) Nov 22 12:19:43 <war> riel: thats what I thought too, yet people still say I do even after I told them what I was using it for Nov 22 12:19:52 <ata> learath: nope 1gb will still win just one app will loose and die Nov 22 12:19:54 <war> riel: I sent the list of my ps auxww (512 processes) and I still had 350MB left over. Nov 22 12:20:05 <riel> war: yup, I saw that
