Iperf does a connect with the UDP socket first….then sends() to a specific
address
Sendto ( broadcast ) is way slower than send()…..in Linux and Windows

Subject: Re: [Iperf-users] When will real UDP, connectionless (sendto(),
recvfrom(), broadcast) be iperf'd?
Not sure why this is needed. I think a UDP socket with bind() using send() is
equivalent to sendto() with respect to both being connectionless at the network
layer. Are you trying to test system or OS calls? If not, I think a bind for
UDP should be fine.
