It depends on your application(s), but if you have a single
memory-hungry program with bad locality, as my experience with digital
circuit simulation indicates, performance decreases dramatically once
your virtual memory requirements exceed the available RAM. We are
talking about orders of magnitude here. For example, when I upgraded
my machine from 16 to 64 M, simulation time shrank from days to hours!
