yeah, that's true, but on older ones (like my toshiba portege 3010 which
has the system maximum of 96MB ) you may not be able to afford the
performance hit either(pentium 266,dma mode0 or pio disk,430tx chipset
and all it's attendant memory performance issues with more than 64mb).

on a more modern unit (like my toshiba 2805 which has 384MB) the
performance hit probably isn't a big deal but I probably don't need swap
that much either.
