[time-nuts] Raspberry Pi 4B Ethernet delay

[David J Taylor]

I did some very simple tests to see how the RPi 4B with its better Ethernet 
connection compared with the earlier model B (rather old!).  My test 
configuration isn't good, as there are a couple of switches between the two 
RPi cards and the monitoring PC:

but the summary is:  the model B reports 0.464 ms mean delay, and the model 
4B reports 0.254 ms, so 0.21 ms better.

Cheers,
David
