Yes, except that Windows ends up raising the effective priority of system tasks that supersede NTP's effective priority. Among the worst offenders, network DPCs and some disk DPCs with some anti-virus programs (i.e., Mcafee). Then, even tasks with real-time priority will and do get starved and an algorithm like NTP's, which has hard deadlines, suffers, thus the inherently higher jitter in Windows. _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
