From niklas@:

Biglock! Most of the logic comes from NetBSD. Also a lot of fixes, enough to get a dual cpu machine actually run MP for a very short while (we are just talking about seconds) before starving out one of the cpus. More coming very soon."
A followup commit improves stability, but only to the point where the init scripts can begin working. This isn't usable yet, but it's getting there. Way to go, Niklas!

    Nice to see things being added, can't wait for the "more to come very soon" part.

    I Hackathon's

    In fact, I never install any release that comes out shortly before a Hackathon, as it's obsolete and missing all the cool features that will come out shortly, and I'll just have to get -current anyways, best to do it in one shot ;)

    This is great news, finally there's being some effort put into SMP! The lack of SMP is the only reason I can't use OpenBSD as a database server, something that I desperately want to do in order to be able to operate on a single platform.

        uhm... "heart" isn't a verb.

        "I heart hackathons" doesn't make any more sense than "I Hackathons"

          Have you never read a bumper sticker in your life, ever?


          Jesus, language purists make me sick.

    I'd like to see UBC before SMP, but I don't get to tell the developers what they are interested in doing :)

        unified buffer cache.
        Just a google search of "UBC+BSD" came up with an article posted earlier on this very site!

    Is biglock ok? Is it the best and most suitable way to handle multiple CPUs?
