On a tux only system, you'll have very little data that is not on a
filesystem. Since all other applications running (you'll wind up with at least
20 or so processes like syslogd...) are very small, and those will use very
little data-pages, you'll probably see no benefit from having a swappartition.
Having enough RAM to be used as a buffer-cache seems more usefull. Unused
code-pages of userland apps will be discarded anyway. Leaving you with more
memory to be used as a buffer-cache.
