Just as a data point, I set up some PII 300 boxes with Buslogic 946
controllers and Seagate wide drives using EtherExpress Pro 10/100 cards.
On a 100bT hub I was seeing over 7M/sec disk-to-disk between the machines,
using FTP. I've also seen good hardware saturate 10bT links, getting
970kBps or more. None of this involves AFP, but these real-world numbers
should set an upper bound on people's expectations for AFP performance
using any transport. Right now I'd settle for my 8.5.1 machine to read
files off any AppleShare server w/o locking up... :(
