As far as I know, your system should be stable. The details of how
much memory/swap is used at any given moment probably depends on your
kernel, how much memory you have, etc.

Do you have any actual evidence of the slow down you mentioned? the
system should begin using swap when/if it needs to. it looks to me
like you discovered the "free" command and are seeing problems where
none exist.
