Yes.  Since paging something in is a couple of orders of magnitude or
worse than reading it from memory, using swap can really slow you down
depending on your hit rate.  Perversely, programs with good reuse(i.e.
libraries) have worse hit rates than monolithic programs because the code
they are executing is all over the place.

I understand the feeling, but have found that the memory has always been
worth it.  Just the other day, I noticed that my Netscape was using 180MB.
One bad programmer is all it takes to abuse your system.

It does work.  If you want all types of interesting behaviour!
