You can get a pretty good idea by observing the machine under
a typical load. Run 'top' and look at the free memory and swap
usage sections. If you are using a substantial amount of swap
space adding RAM will help greatly. If you have a large amount
of 'free' memory now, adding more RAM won't help. If neither
value is large, more RAM may help but it probably won't be
dramatic.
