If you are asking a non-NTP question then this really is the wrong
place. Our discussions of network latency are around the effects that it
has on NTP calculations and the error budget.

My only other comment is that local data is always faster (unless you
have really slow disk drives) so why are you asking in the first place?
It can't be just about the network latency.
