Dear Magnus, I do not have a reference for the performance of Windows as NTP server. This has been a busy week and long working nights. It is a logical workload after being absent for nearly two weeks : )
I will browse the web and NIST to find some solid references to this issue. I am still enthusiastic about doing the side by side comparison for measuring various parameters between a Windows and a Linux box running NTP. It will require time to set the test but the contribution could be interesting, specially if no work has been done previously. I will use my spare time this weekend to search for information on the subject.
