     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."
