*BSD had (useful) IPv6 long before Linux thanks to kame. OpenBSD is also the last of them to get SMP support, even if it's pretty fresh in NetBSD too (a year or so).

haha nice try, 4.x DOES have smp.
I have mod points so I actually researched the AC to see if he was right or wrong. Rather then waste them on an AC though I figured I'd actually post a link to back up his claim: FreeBSD Symmetric MultiProcessor Kernel.

Nice troll, FreeBSD 4.x does have SMP although it's pretty inefficient. 5.x has much better SMP but it's currently labeled "new technology release" and they recommend 4.x for production servers. 5.x is quite stable though..

That's actually crap. They use the university of alberta's server as it has more bandwidth available to it than their own connection.

Also, I belive that NetBSD already has SMP support (not sure when it went in there, though). So does Darwin, of course.

"www.openbsd.org and the main OpenBSD ftp site are hosted at a SunSITE at the University of Alberta, Canada. These sites are hosted on a large Sun system, which has access to lots of storage space and Internet bandwidth. The presence of the SunSITE gives the OpenBSD group access to this bandwidth. This is why the main site runs here."
And even given this, ftp.openbsd.org is usually very slow around release time.

Perhaps you should do your research a bit more thoroughly next time. The link you are referring to is about FreeBSD SMPng (ng = next generation, implying a previous generation). SMPng is a core tech of FreeBSD 5.x but SMP has been a feature for 4.x a long time.
From the page you linked:
FreeBSD supports Symmetric MultiProcessor kernels in the following releases:

OpenBSD is NOT premirely a webserever. It can and is used as one (I do it), but its main use is as a firewall. It even got voted as "best application for firewalling" by the MS crowd..:)
I've been aware of OpenBSDs lack of SMP since 2000 when I installed it on a double PentiumPro 180 Mhz. I Thought it was weird it didn't have SMP since Linux and FreeBSD had it but after some reading I accepted the desision.
I guess the OpenBSD guys went for SMP considering the double core desktop processors gaining more ground. Am I correct?

Ok, I have mod points and I have to comment on this. I can say without a shadow of a doubt that the OpenBSD team does not do anything at the whim of the bitching masses. Did you not read the recent mailing list thread about the decision to stop updating Apache in the ports tree??? And what about when they removed ipf???
Theo may be a hard headed son of a bitch but he takes care of buisness and is not swayed by popular opinion. This is not a sudden development, there were articles a year ago about how the OpenBSD team was looking for a full time programmer to work on SMP.
This has been planned, and when OpenBSD executes a plan they execute it well.

Since OpenBSD SMP support is mostly NetBSD's plus code style changes, I'd say it only took 4 months to import what was started 3 or 4 years ago by Bill Studenmund for NetBSD.
Oh, and I forgot, removal of all ACPI code, too.
That means OpenBSD won't work with MP computers that have a broken MPBIOS or simply require MPACPI (like most, if not all, HyperThreading processors do).

OpenBSD's focus is vastly different from Linux's (I use both, and I use them where appropriate). OpenBSD's primary focus has been on security and correctness of the implementation. Compare OpenBSD's pf with Linux's iptables - pf is so much more powerful and useful than iptables the difference is like night and day. The OpenBSD pf has security features that cost large sums of money in the closed source world.
SMP simply is not a priority for OpenBSD. The kind of uses OpenBSD is put to hardly ever requires it, so it's not in the least surprising that they are only just implementing it now.
