What sort of network interface do the servers have? If the server is a Mac
Plus, I would think that it has a LocalTalk interface. It doesn't matter
how fast you can receive data if the server can only send it at
230kbit/sec.

(approximately 50% of LocalTalk bandwidth. Note - theoretical throughput
for LocalTalk is >95% of bus speed.)
I just copied a 2Meg file from a server (Mac II, some sort of Northern
Telecom big disk with built-in backup) to my Mac II (Apple Ethernet card,
using MPW duplicate) and got a data rate of 42890 bytes/sec, or
343Kbit/sec. Not astounding, but better than 15kbyte/sec.
