Reducing the latency has no direct impact on the jitter.

There is a second order effect that depends on the network loading.  If there 
is other traffic on the parts of the network used by your NTP traffic, the 
queuing delays will be shorter with a faster network.  On a lightly loaded 
network, the difference will be hard to measure.

There is a much bigger potential problem with gigabit networks.  In the early 
days, the per-packet interrupt overhead was excessive so they batched 
interrupts.  That can cause delays and jitter.

Do we have a clear description (or link) for how to disable that?
