No, all I am doing is sending datagrams out the interface. Since this is
UDP, I don't need anything to be receiving the datagrams (the sender
doesn't care if they get there). I am just looking for the maximum rate at
which I can send them.

iperf -c 127.0.0.1 -i 1 -b 1000m -w 256k -l 1024 iperf -c 127.0.0.1 -i 1 -b
1000m -w 256k -l 1025
