You could estimate what a "dumb sender written in C" could produce: On the receiver box, do: # apt install netcat-openbsd $ nc -k -u -l 6666 >/dev/null On the sender box, do: # apt install netcat-openbsd pv $ pv </dev/zero | nc -u receiver_ip 6666 and see what speed pv will show to you. On my old Intel E8400 Core2Duo machine I get circa 900MiB when transferring between a two endpoints on the localhost using a pair of netcats. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
