Netbeui is more efficient on a single point to point link, however it resolves everything by braodcasts and those broadcasts creep up as more machines connect to the net. It has been along time since anyone I know have has credibly evaluated the relative merits, but generally I beleive the Braodcasts associated with Nebeui start to cost more than the gains from the rest of the protocol at between 10 and 15 machines, by 25 broadcasts overwhelm the rest of traffic and above that NetBeui is basically a slug. NetBt (Netbios over TCP/IP) suffers similarly, EXCEPT that M$ has incorporated numerous measures to reduce broadcasts, including WINS servers. Finally you can drop NetBt which M$ is probably doing next (W2K and WXP no longer require it) and resolutions are accomplished primarily using DNS. TCP/IP is a broad and powerful protocol, it will certainly be out benchmarked in a variety of narrow cases, but no protocol works over the wide range of condictions and topologies that it does. Further M$'s implimentation of NetBeui was extremely well optimized at one time. There implimentation of TCP/IP still is pretty weak.
