Well, but you know that the U in UDP means unreliable?

On a non-congested link, UDP packets should arrive at the receiver,
but the application has to deal with packet loss, since it cannot
be sure that it is used on a reliable link. Packet loss will cause
reduced throughput (as with TCP), unless it can be dealt with by FEC
or other means (which also reduce throughput).
