Make it as large as 5 times the expected maximum udp packet.
Increasing the buffer size may be a good idea on Windows. But setting a
buffer size is usually a bad idea on Linux in my experience (the kernel
knows better).
In any case, PACKET size over 65535 bytes makes absolutely no sense. It
is not possible at the protocol level (unless jumbo grams maybe but
nobody uses that for multimedia if at all).
