Any percentage is assuming dedicated, IMO.  25% might be the more common
number, but you're still assuming that you can have your pick of the
machine's resources.

My idea of "not dedicated" is "I can launch a dozen postmasters on this
machine, and other services too, and it'll be okay as long as they're
not doing too much".
