We are using the DACU on ethernet here at BU on our 3081, transfer rates seem analagous to UNIX::UNIX transfers and are likely limited by the remote end (eg. VAX.) That is, tranfer rates using FTP on a clear day will oscillate around 20KBytes/second (as reported by FTP), obviously oscillating wildly for very small files. If someone wants me to run a few experiments through it send me a script and I'll send you the results. I agree this DACU/WISCNET thing is not the last word by any means in IBM/TCP and I encourage Art's group and would be very interested in what they develop but you can just write a check and wait for delivery, I suspect it will serve many people's needs, you will have to decide that for yourself, your mileage may vary.
