I was wondering about Rich's results. Any link in the chain (sender,
routers, receiver) can drop a UDP packet. I've never stressed networking
enough to know what happens if you just send packets flat out. Maybe your
own OS is dropping them when it gets overwhelmed (like when Rich's results
got much less network utilisation on going from 1024-byte packets to 1025).

I can't see how an app could meaningfully do anything with the data
arriving from a flat-out gigabit network (16 microseconds per 1024 byte
packet at 50% utilisation).
