Solbourne had it's OS/MP which did do SMP with a subsystem locking
strategy. This worked reasonably well for the time. So it was quite
possible. Solbourne died, though because it couldn't get Solaris sources
soon enough to do a port that mattered...

I'd agree, 2.4 was pretty slow and chunky, 2.5 was alright, but 2.5.1

quite usable and stable.

Yeah, to
be fair, by the time Solaris 2.3 or 2.4 came around, it was
mostly up to par. (Or maybe it was because Moore's law meant that we
didn't care any more. :-)
I have some vague memories that we had to do something like double the
RAM in our SPARCstations to make Solaris 2 feel comfortable. At the
time, that was a pretty serious outlay in an academic department.
2.5.1 felt like the first version that was _truly_ usable. Also by this time, the hardware was going in
directions that SunOS
wouldn't keep up with.
Yeah, Doug is right, SunOS was pretty simple, it didn't really take
advantage
of SMP, Greg Limes tried to thread it but it was too big a job for one guy.
That's not to say that SunOS couldn't have evolved into SMP, I'm 100%
sure it could have. It just didn't. It's a shame.
