> Note that even the bytes version is still quite slow. UDP is used for light-weight protocols where you may send thousands or more messages per second. I'd be curious what the sendto() performance is in raw C.

Ah, I wouldn't rely on the absolyte values, my computer is *slow*.

On a more recent machine, I get this:
100000 loops, best of 3: 8.82 usec per loop

Whereas a C loop gives a 4usec per loop.

Sure, but why do getaddrinfo() and gethostbyname() return strings then?

This means that someone using:

addr = getaddrinfo(...)
sendto(DATA, addr)

Will pay the idna encoding upon every call to sendto().
