new memory = more swap?

Matt,
  I have heard of systems getting doggedly slow with too much swap enabled.  If this is just a work station, I wouldn't go past 256MB of swap.  If you're working with huge databases, that's another issue.

she's crashing her car in an intersection
she did not see the light
she's walking round and round in a shopping mall
as if she had no sight
dreams are only clouds that form and dissipate
the sky is a highway for metal birds
and land is real estate
she does not understand
her world depends upon a history of lies
she walks right by all her old high school friends 
for she has dollar signs in her eyes
