Any idea why with TCP I get 828 megabits on my gigabit connection but only
1.05 megabits with UDP?
Using iperf to benchmark.
TCP
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)

UDP
------------------------------------------------------------
Server listening on UDP port 5001
Receiving 1470 byte datagrams
UDP buffer size: 101 KByte (default)
