Oups, I meant: "hold on the _sender_". Sorry.
Actually for TCP, you _also_ need big enough buffers on the receiver,
but for a different reason/different "window": the sender won't take
the risk to overflow the receive socket buffer. So if the receive
socket buffer is too small, the sender may refrain itself to use all
the available bandwith.
But this not related to UDP/your question.
