That could explain why I see higher NTP jitter on a Windows system

Possibly, but USB, as a polled, token-ring like protocol, will always
add jitters in this case.
Thanks. I don't understand enough about USB - do you have good reference?
If one would stop all unpredictable processes in Windows one would
have to stop Windows. Can one stop network and disk I/O in Windows?
IMHO, if one wants a good, consistent NTP server, it should at least
be Linux.
HTH
Well, it may help the person who needs to run simulation software which is
Windows-based, in that if timekeeping is very important to them, it
suggests running Windows on a virtual machine running under an accurate
FreeBSD host. I wonder whether that would provide any greater accuracy
than native Windows NTP? My gut feeling is "obviously not", but I wonder
whether tests have been done....
Cheers,
David
