"The NetBSD Foundation announces that it has hired Andrew Doran to work full-time on improving symmetrical multi-processing in NetBSD. This work is made possible through a generous donation by Force10 Networks and internal funding by The NetBSD Foundation. Andrew Doran is an independent, Dublin based Unix systems consultant with special interest in building scalable systems. He has been a NetBSD developer since 1999 and is currently working on the transition from a big-lock SMP implementation to a fine-grained model, which allows multiple CPUs to execute code in kernel context simultaneously. Hiring Andrew full-time will boost work in this area, with the final result of a SMP implementation that is ready for tomorrow's multi-core-CPUs."

Yes it'd be nice to see some new benchmarks. I don't believe anyone has done anything more recent.
I believe SMP is somewhat weak on NetBSD & OpenBSD and OK on FreeBSD 6.2 but I can't verify this to be true without seeing benchmarks.
FreeBSD 7 will give a *real* boost to SMP performance & turn things around.
A couple of benchmark results provided by FreeBSD:

The performance difference in SMP bind from 6.2 to 7 seems VERY IMPRESSIVE.
Another short article talking about SMP on FreeBSD:

I'm hoping someone will provide independent SMP performance benchmarks once FreeBSD 7 is released. And compare it to NetBSD, OpenBSD, DragonFly & Linux.
Though DragonFly is not one of the popular choices I'd like to see how it performs because it is handling SMP differently. ( more out of interest ).
