My 24/7 RAID1 system boots with swap enabled, but usually one of the first things I do after boot is swapoff -a. Dedicated swap on systems with ample RAM seems to me to be an anachronism.
Not at all. My server systems have beetween 4G and 16G of memory, all have and all use swap (even if just a tiny bit). My new office systems have 2Gb and use swap - the older boxes only had 1Gb, and also used swap. If for instance you've got lots of stuff in KDE that you never use (I can count quite a few processes that I have no idea what are for), they end up being swapped out permanently, and the memory is available for the part of the system that I actually use.
The way I remember it, if no dedicated swap partition exists, kernel will swap out to /. Right now on my 2.6.31 system referred to above, which has 4G of RAM and no swap partition enabled, with 5 web browsers with 100+ tabs open among them, and several other X apps open scattered among 6 virtual desktops, and Apache running in background, 51% of RAM is consumed by cache. I really don't see the point of having dedicated swap partition(s) on a typical desktop or laptop system. -- "The wise are known for their understanding, and pleasant words are persuasive."
