This question, along with other recent discussion about swap, leads me
to ask a question in response: Why is everyone so concerned about how
to get away without swap?

Hard drives are cheap. Why does your server with potentially 10GB
(!!!) of RAM have a hard drive so small that you can't sacrifice a few
GB for swap?

I'm really curious.


SATA Hard drive speeds - 70 megs to 150 megs a second unless you're RAIDing
DDR2 RAM speeds - 6000 megs a second and up.

If performance is a key issue, which I'm sure it is, you don't want swap.

In which case the real question is not "how much swap do I need?" but
"how much RAM do I need to avoid swapping?".
