Just to stick my $.02 in here and stir up the pot.....  let's talk
mainframes for a minute.

On IBM mainframes, if you can turn off the Dynamic Address Translation
(required for virt memory and swapping) then you can achieve some real
gains in machine performance.  All jobs run in 'real' memory and the
hardware doesn't need to screw around with address translations.

Can this same thing be done on the i386 architecture?  I doubt it and I
would doubt that Linux would be able to pull it off.  But Linux never
ceases to amaze me.

In any event, there *is* the possibility of performance gain if address
translation can be turned off.
