The reported +time is the *difference* between the time to run the program +with the benchmark input and the time to run it with no input. +(This procedure ensures that implementation dynamic languages are +not prenalized by startup time.) A median of ten runs is taken. The +process is reniced to a high priority so that the system doesn't +interrupt runs. |
