On most operating systems the UDP buffer is 64 Kb by default.
Additionally, one has to consider that the buffer is organized in pages
of 128 bytes or 256 bytes respectively. If the trap you are sending
has a length of 260 bytes, then the buffer will be able to hold
128 traps. Which is not that much...
