An interesting question. I had always thought that SMP was (one of?)
the technical reasons why Sun moved from a BSD to a System V base.
Since then, of course, we've done lots of work on SMP support for at
least FreeBSD. Does anybody have an overview of how good the support
is compared to modern Solaris? Is there any intrinsic reason why one
should be better than the other?

I'd agree, 2.4 was pretty slow and chunky, 2.5 was alright, but 2.5.1 was quite
usable and stable.
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.
