You should be careful about using datagram sockets -- my understanding is that there is no guaranteed delivery when using datagrams, unlike when sending via normal sockets, and so you can lose packets and never know it.
As for the speed issues someone was seeing under OS9, a long time ago I built a web server using pre-OSX (it was even pre-OpenTransport), and the speed was absolutely fine. (I've also been using a net app under OS 9 on my OSX box, and it runs just fine.) One guess about the problems you're seeing is that it may not be getting enough cycles to connect, read, write, etc. If you're sitting in a tight loop waiting for a socket connection, or waiting on a send or receive, try using the callback message forms instead. (And if you're already using the callback messages then I'm not sure what to tell you.)

In Classic mode, all networking has to be rewired to go through OS X networking protocols, so that's one explanation for the delay. Another is that MacOS pre-X never had a really robust TCP/IP stack, and was alywas a bit on the slow side. But maybe someone else can offer you hints on speeding things up.
I also discovered that I got a huge speed increase if I used datagram sockets instead of normal sockets.
