I vaguely remember mention on this list of a tool that soaks up as many cycles as it can get to obtain an accurate measurement of the true system time. Can some one give me a pointer? I've had no luck with Google... thanks, Torrey Hoffman thoffman@arnor.net torrey.hoffman@myrio.com ^ permalink raw reply [flat|nested] 3+ messages in thread
