I don't think any formula for the "right" amount of paging space
is terribly useful. If the machine has 8GB RAM, it's probably
doing something important, which means it should have been spec'ed
to avoid paging altogether.

The comp.unix.aix FAQ is a large and mostly useful document. Did
you read this section before posting?

2. How much paging space do I need?

Nicholas
