Greetings, all. I've been challenged to show some evidence that ntpd running
on a VM (as a stratum 2 server in a company-internal pool) really does
perform differently than on bare metal. Can anyone point me to any
non-anecdotal scenarios or tests that might help demonstrate the
performance/accuracy differences? One thought I had was to make a small
cluster of several VM servers and several bare metal ones and add all of
them to some clients and simply observe deltas in ntpq stats. Does anyone
know of other good ways to get some "apples-to-apples" comparison data?
Thanks
Dan

Dan,
For what it's worth:
Windows-10 "bare metal" GPS/PPS synched:

Windows-XP running in a VM on the above hardware:

I don't have a comparison for Linux, and you don't specify what OS you wish
to use. What sort of accuracy do you need?
Cheers,
David
