It may be the (64 bit) qualifier is key. I know 32-bit ntpd runs on x64 Windows, but I have no experience to know how it compares to running on 32-bit Windows. I wouldn't expect much of a difference, and perhaps others can share their experience with ntpd on 64-bit Windows. On 32-bit Windows, my experiences have been very similar to David Taylor's. I would expect sub-millisecond jitter relative to your GPS source 2ms away, if care has been taken (such as disabling interrupt coalescing on gigabit ethernet cards). Good luck, Dave Hart _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
