Yes.  You should be doing your intense I/O (suping, serving, anonymous
ftp) on a seperate server machine, and dedicate a machine to
development that isn't serving all the network requests.

Of course, that's the ideal scenario, and it's not quite as easy as it
sounds when you're using your own equipment.  But if you could dig up
an old 386 to serve the foreign net users, that would probably take a
large load off sun-lamp.
