1.53 [2003-12-30] - Windows: higher resolution time() by using the Windows performance counter API, from Jan Dubois and Anton Shcherbinin. The exact new higher resolution depends on the hardware, but it should be quite a bit better than using the basic Windows timers. #### use Time::HiRes qw( time sleep ); my @times = map { time } 0..200; #my @times = map { sleep(0.001); time } 0..200; my @time_diffs = map { $times[$_] - $times[$_-1] } 1..$#times; $, = "\n"; $\ = "\n"; print @time_diffs;
