On the other hand, I think he said he was using AppleTalk. AFAIK, the only AppleTalk protocol that does similar windowing is ADSP (AppleTalk Data Stream Protocol), and it doesn't do nearly as good a job of it as TCP. And there aren't very many higher-level services that rely on ADSP; most things (including the AppleShare File Servers) use ATP (AppleTalk Transaction Protocol) which is for all intents and purposes *designed* for poor performance. Typically the real reason you can't get maximum utilization of a fast network connection for file transfers has NOTHING to do with the network performance. Usually it's a matter of the performance of the file system.
