That is not a useful indicator. Mine says
Filename Type Size Used Priority
/dev/hda5 partition 1028120 87336 -1
Size is just the created size of the swap partition and is not related
to how heavily it is being used. For that information, look at the
value under "Used". Sometimes a more useful command is "free" which
reports amount of real and vitual memory being used. And you don't
have to be root to run it.
When your system starts running slowly, run the "top" command to see
which process(es) is consuming the most resources. "man top" for more
information. That, too, can be run by mere mortals.
