The latter. You've paid for it, so you use it :-) Linux doesn't
handle
memory in the same way as windows does. It uses all it can get, just
releasing whatever it needs to, whenever it needs to. The time to
worry is
when your swap is also used up :-)
I've just been running some heavy processing work, and my swap had
220MB used.
Most of the time it isn't used at all. IOW, my box works well for
ordinary
work, but is somewhat underspecified for the heavier processing.

Use the command free to see how much memory is used as cache and how
much is actually in use by processes.
