Please fix this bug. ------------------------------------------------------------------------ [2013-06-16 04:02:52] yaro at opti dot su The same problem occurs in PHP 5.4.15 too! Why developers ignore such an important issue? ------------------------------------------------------------------------ [2013-04-12 14:22:32] phpbugs at musiclogistics dot net @ab@php.net: You are right: While usleep() only works in 1/64 second increments on my machine (640 loops of "usleep(1)" take about 10 seconds), this is not related to PHP 5.4.14. It's the same on 5.4.13 and probably a limitation of Windows' multitasking. ------------------------------------------------------------------------ [2013-04-12 11:29:36] pajoye@php.net We should use performance counters instead, which brings a much higher precision at less cost. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
