speed of light
The absolutely fastest a particular algorithm or application could be
implemented, given a set of constraints that are assumed to be
unchangeable. For example, "This would take 60 microseconds without
any processing whatsoever, so that's the speed of light." However, as
one brilliant hacker once commented: "Remember that the speed of light
only is constant if you can't redesign the universe."
