You are quite right of course. You may wish to tune things so that you
are not swapping to the same disk that your apps are hammering on for
I/O too
Still memory is cheap these days so much swapping is a bad thing most of
the time that can usually be cured by throwing more ram in the box. I do
tend to let virtual machines swap a bit since the underlying host will
be using any free ram it has left to cache Disk I/O anyway.
