Are you sure? I thought that at first, but those numbers are time rather than speed, and when I checked my units carefully it seemed that he was correct: new_spd = x% * old_spd => x% = new_spd / old_spd new_spd = 1 test-suite / 1.432e9 cycles old_spd = 1 test-suite / 9.539e8 cycles x% = (1 test-suite / 9.539e8 cycles) / (1 test-suite / 1.432e9 cycles) = (1 test-suite / 9.539e8 cycles) * (1.432e9 cycles / 1 test-suite) = 1.432e9 / 9.539e8 = 1.50 = 150% Where am I going wrong? --Josh -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
