    SubjectRe: Swap vs No Swap.
    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 12:18:41 <war> riel: For a single user system.
    Nov 22 12:18:43 <ata> war: what are you trying to do ?
    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
