It does not use swap pages unless they are needed. Swap pages are slower than ram.

The kernel does not use swap until all ram is exhausted. Ram is fast. Swap is slow. 
Swap is 
supposed to be a backup for low memory. It's slow. But, what it has become is a cure 
all 
of underprovisioned machines. 

I'm going to lunch :) If there is any more discussion about this I'll reply when I get 
back.
