I can get throughput in the neighborhood of 4MB/sec. between my Alpha UDB and a P150+ over 100-Base ethernet. Both are running 2.1.90 kernels and fitted with Netgear FA310TX "tulip" network adapters.
However, there is room for improvement. At work, I administer a cluster of AlphaStation 600/333 boxes linked with 100Base, and have measured almost 10MB/sec. copying large files between them! Granted, we're talking expensive machines, Digital Unix 4.0 and NFS-v3 but, hey, it's something to shoot for <g>.
Some of this gap could be closed on the Alpha if Linus would unroll the inner loop of his Alpha IP checksum code a little bit more ;-)))
Actually, Richard Henderson and myself were tinkering at one point with ideas to really make the Alpha IP checksum code scream....
