No actually I meant swap, but what I said isn't very clear.  I didn't 
mean adding _more_ swap will improve performance but rather that even 
with a lot of main memory that having swap (as contrasted with *no* 
swap) will improve performance.  The reason is that stuff in application 
memory currently not being used will be swapped out making more room for 
disk cache and buffers.  OTHO, the question of just how much swap is 
desirable is another question.
