No, unless you're comparing to Ethernet.

I think you're right.

Sounds like a problem with Solaris. The chip is easily capable of over
1 Mbps. There's a commonplace existence proof of the ability of the
Z8530 to do over 230 Kbps -- that's what was used for LocalTalk
(low-end physical layer of AppleTalk, originally simply called AppleTalk)
on most Macintoshes from 1984 to the mid 1990s.
