>> I think gig ethernet has a higher delay for smaller packets (ntp's udp >> datagram is tiny) than 100mbit ethernet.
> There is very little to support this claim. Most gig-ethernet chips try to save CPU cycles by batching interrupts. There is usually some way to turn it off. I don't have any numbers handy, but I wouldn't be surprised if that made the observed round trip times slower than 100 meg ethernet. Most UARTs have similar logic. -- These are my opinions, not necessarily my employer's.
