Unused things in RAM will get swapped in eventually, and swapped out
when needed, and this isn't usually a problem. For example, if you run
Apache locally but never visit  http://localhost, it'll get swapped.

The problems arise when things in use have to be swapped for another
thing in use, then vice-versa, etc.

Look in /proc/vmstat:

grep pswp /proc/vmstat

This gives you the number of kB swapped in/out per second. It has to be
low :)
