The Xircom is pretty bad, as it costs a lot to do the I/O through the parallel port. Just using TCP/IP sockets (no disk access or processing) the machine can send and received about 42KB/sec. A better adapter can do nearly 3x that on the same machine.

So about 1Mbps max with a good adapter? Wow, more than I thought... yeah, a hard disk of the era, not even AT bus, most likely won't be able to keep up with that, heh.
