  1. Re: OpenBSD... on A Tale of Two Systems, Linux, xBSD · · Score: 1

    Not that this would be really important ...

    OpenBSD was derived from NetBSD and still shares most of NetBSD's "artifacts."

    Ever tried to login and do work on that machine when the load was higher than two? Could that feeling be described with "sluggish?"

    2. Multiple sources - yes. And the OpenBSD software was written completely by a small team? Sounds more like an "argument" for closed source groups rather than promoting the OpenBSD auditing efforts. Fortunately, the findings of OpenBSD also benefit other freeware O/S.

    3. How do you think Linux distributions are created? If you are so hot on having packages, you can get your packages only from one source (i.e. the distributor). Think of xBSD as one distributor who happens to maintain all the software he distributes. You really don't need to poke around ftp sites to get software for Linux. Really, you don't.

    4. Linux isn't focussed on the desktop, even if many BSD people claim to be it so. Some distributors are out for the money of the masses and that happens to be the desktop. That's true. As a counter example, Caldere developed a whole suite of Netware software for Linux, software which is targeted at the server market.

    More opinions of yours:

    Because it is easier to install and maintain than Linux

    "The Linux" doesn't exist. You seem to be confused about this point completely.

    Its development is less chaotic, and I worry less about it.

    Hu? If you are not worried about development, why do you care about it at all? You seem to refer to the core team, the king of kings (ah, committers), the elite, etc. Again, imagine how controlled development in Redmond is.

    And then comes more blabla.

    The final note (at least you didn't say Linux there) is also not that intelligent - see the ongoing thread about UIs and installations on freebsd-hackers and you will see what I mean.

    NFS is an insecure and scary way of doing things.

    NFS v3 is (to quote Alan Cox) "NFS done right." Unfortunately, it's still a long way until NFSv3 will be available in the free OSs.

    There are some environments which need networked filesystems. If NFS is the only thing every OS in their environment supports, they have to live with it.

    Nope, you misunderstood me.

    NT is theoretically a mini kernel. This means, the kernel provides only the minimal amount of services, everything else is done in subprocesses.
    This provides an easy way to scale on multiple processors without all these problems normal kernels have to cope with (fine grained locking).

    SunOS isn't a mini kernel. But they have gone through the trouble of making their system actually scale better than NT currently does.

    FreeBSD has very old, clumsy code. Matthew Dillon (FreeBSD coder) put it so:

    I like to call it "algorithmic rot". In otherwords, after a decade or
    two the kernel just isn't the squeeky clean implementation it could be.
    I get screamed at a lot when I try to clean the rot up, because half the
    time it involves not only documenting code but also rewriting routines
    that don't actually contain bugs in order to prevent future rot. Kinda
    like wood sealer. The KASSERT()s work that way too. You put them in to
    force out the bugs and to prevent new ones from entering.

    -SMP: not so good

    In my experiance (I have a dual celeron at home) freebsd is as good, or perhaps better than linux when it comes to SMP.


    There are some old land lords in the FreeBSD team who claim that the global kernel lock would be enough for superior SMP support.

    Terry Lambert, old advocacy freak, once wrote that neither, Linux nor FreeBSD would ever support SMP as systems designed from the ground up.

    Yeah, sure, Solaris will never beat NT.

    Solaris scales up to 64 processors (in reality). NT, the New Technology OS, scales up to 16 processors (in marketing). Solaris is so much "worse," because it wasn't designed with SMP in mind.

    The recent benchmarks have shown that the lack of a multithreaded network stack in Linux lead to a win for NT (no pun intended) when dealing with multiple NICs. That also obviously demonstrates that a global kernel lock cannot suffice.

    Currently, Linux fine grained locking in 2.3 is superior than that of FreeBSD 4.0-current. Let's see whether FreeBSD will catch up.
