SMP support in FreeBSD seems to be a perpetually favorite feature

if I should go with dual procs or just a single. The AMD64x2 is
slightly cheaper than the FX-57 so I'm leaning that way, but it
would be a rather pointless savings if SMP isn't well supported.
So, is SMP in -STABLE ready for primetime? Can it really make use
of two processors?
Sigh. You know, I've been running with two processors since 4.1 or
thereabouts. Sure, the BGL scheme is inefficient as far as the
kernel itself is concerned, but for compute-bound user processes it
worked just fine. Naturally I avoided 5.0/1/2 for my production
boxen, waiting for the complete overhaul of SMP to stabilize, but
when I booted 5.3, everything was fine and I haven't looked back.
Personally I don't have the first clue what people have found to
gripe about. It has been good, it got a _lot_ better in 5.x, and
it's continuing to improve.
Ports to new processor families are an entirely different kettle of
fish and have their own sets of problems, virtually all of which
have to do with the new architecture and not with the general SMP
support itself.

I agree. I'm not a FreeBSD expert by any means, but I do enjoy using
it very much. I've learned a lot about it over the past year or so
that I've been running it. I have both a 4.11 and 5.4 box that have
dual processors and are running like champs. The 5.4 box is doing a
lot more work actually, and it never has a problem. It's been all
good for me, but then again, I probably don't delve quite as deeply
into some of the complex heavy loaded things other do.
