Unless you have done something not very smart like putting a DB on your
asterisk machine, reniceing asterisk isn't going to give you more clock
cycles.

What did you expect to get by that? Linux will swap out anything not
being used but will keep what it needs. What you have done is make it
more likely in a crunch, your machine will fall over instead of trying
to gracefully handle the load.

Swap in ram? Why not use the ram for ram?

Sounds like you need a beginers book on OS design or even a simple
linux/unix admin book.
