Open Source OS Benchmarking Competition 314

BenchmarkingFreak writes "OSnews is running a story about a new benchmarking competition: OSU Open Source Lab wanted to take the concept of benchmarking a little bit further with the Beaver Challenge 2004. In this competition they will be allowing a community of experts in each OS to tweak their configurations to ensure maximum performance. And they are running it all on wicked machines, just imagine... well you know."

    We have selected the following distributions. This list is not final and if people want to ante in to try this with their favorite distro, let us know at bc2004 at osuosl dot org or in #beaverchallenge on the Freenode.net IRC network.

    * Debian GNU/Linux
    * Fedora Linux
    * FreeBSD
    * Gentoo Linux
    * NetBSD
    * OpenBSD
    * Red Hat Linux
    * Slackware Linux
    * SuSE GNU/Linux

    Where's Mandrake?

    • Mandrake is more of a "user friendly" distro then a performance optimized distribution. Someone might add Mandrake to the list, but it's not as tightly configured as say Gentoo and I can't imagine what purpose it would be to add it to the competition except for just representation.

          I've never used Mandrake but didn't it start out as a version of RedHat compiled for the Pentium instead of the 486?

          First it was based off debian. The real motivation was KDE. Of course the first Mandrake I used was based off Redhat and I used Gnome. It was compiled for i586, but more importantly for me as a developer, it had more up to date packages. This meant I only had to upgrade the components I was working on and not every library it depended on. I still use Mandrake at work, but at home where I do more tweaking I use Gentoo, which is too bleading edge for day-to-day, but great for developing for newish hardware. I tried Gentoo on my laptop, but while it was faster, it was too much work to keep up to date, so I went back to Mandrake. My main box at home just runs a script every night to keep up to date, it wouldn't be a big deal if it were rooted so I sleep well at night.
          • First it was based off debian

            Hmm, interesting, did not know about that. Mandrake does use Debian's menu system, but the first version [mandrakesoft.com] I heard about was 5.1, and it was already based on Red Hat, which I think was at version 5.0 at that time, thus the version number.
            • The first version I recall is 5.1 was which indeed based on Red Hat. From the Mandrake 5.1 release notes.

              "Linux-Mandrake is an updated Linux-RH 5.1 GPL, with KDE 1.0 fully integrated and preconfigured in it. Those two parts have been (not so much) modified and improved to work properly together."

          Much of the functionality is similar too, the menu structure for the WM/DM is Debians, and the package manager is urpmi. URPMI is like apt where it has server lists and does automatic dependancy resolution, checks package signing, and allows autmation of the install. But underneath URPMI is still RPM; the file system a

    This is a really neat idea, and it's a long time coming; however, I wouldn't expect overly divergent results among Linux distributions. Afterall, they're all going to use the latest 2.4 and 2.6 kernel and comparable glibc versions(with maybe the exception of Debian), so the only speed difference should be in the compiler flags used to build the packages. I'm not trying to negate the coolness of this competition because it should give a good measure of performance between the BSD distros VS Linux distros, but don't be surprised when the Linux distros all show comparable results. As a footnote, I do expect Gentoo to come in the lead of the Linux distros having tried them all and found it the fastest in empircal testing...

      However, I wouldn't expect overly divergent results among Linux distributions.

      Whoever puts their apps in the latter sectors of disk and uses the first sectors for writing will win by a margin of 2:1, provided no one else does the same. On the other hand, if one group makes use of a nice mfs and no one else does then that group might win by a much larger margin. Depending on the test, selective use of processors or placing swap in just the right space may make a big difference as well. Maybe it'll depend on which team gets a Hacker to, in 3 days, recode specific routines in assembly just for that processor setup.

      In short, welcome to the real world of benchmarking: whichever team figures out how to bend the rules just right will win.
      This kind of benchmark rule bending happens quite often when the big players get rfp's for large orders from bigger players, and ppl make lots of money figuring out how to bend the benchmark rules, even when those rules cover well over a hundred pages of specifications.

      • Are you saying it's a good idea to partition / at the *end* of the disk? That sounds like an interesting thing to try, actually. Traditionally I've always had it somewhere near the start, after the swap and boot.
      • In short, welcome to the real world of benchmarking: whichever team figures out how to bend the rules just right will win.

        Very interesting. It would be cool to have a benchmark with five times exactly the same distro, except the competing teams don't know this.

        It would be nice to see if the differences achieved were comparable to what the differences between distros will be in this test.

I loved LFS, since it taught me quite a bit about the nuts and bolts of a Linux distro; however, I ended up writing my own package management scripts, which became tedious to maintain. Gentoo fills this hole perfectly; it has the "build your own" feel, but makes the package management a doddle.

      Nice Troll. You had me going until this bit:

      I do expect Gentoo to come in the lead of the Linux distros having tried them all and found it the fastest in empircal testing...

      Beautiful.

      Back a while, when gentoo was still had the smell of pop novelty, you would hear all this great stuff about how gentoo distros were the fastest, something about being able to specify --funroll-all-the-bad-loopies and --enable-r0xor-opts and --omit-random-instructions to the compiler. Of course, all these claims of gentoo's speed have never been backed up. On the contrary, the only results we've seen published tend to indicate that you average gentoo distro is composed of slower-than-average or average applications.

      These days, we hear the new mantras of the gentoo-fanboys: it's not the speed (good thing!) that they use gentoo for, but instead the ease of use or robust package management or configuration flexibility. That's great and all, but it's all a bunch of green-is-my-favorite-color kind of advocacy: opinionated, unsupported, and unconvincing. People who've gone through the long laborious pain of installing gentoo (reminiscent of slackware 3.0 and libc upgrades, what year is it again?), and then having wasted the effort on a system that will probably spend more cycles compiling itself than serving the users, they justify the waste with a belief that their system is better managed or more finely tuned or whatever. Emphasis on whatever.

      Of course, none of the supposed benefits of gentoo are backed with anything approaching rigorous analysis. Instead we get vague anecdotes and slashdot fanboyism. When we inevitably learn that the gentoo portage system is riddled with problems, conflicting package maintenance mechanisms and policy, broken and overtweaked package scripts, and that the whole thing needs a certain amount of voodoo to work, the gentoo boys will probably come up with some other reason why it is the one distro to rule them all.

      The rest of will just wait for the results of your empirical studies with smiles on our faces!

          Advice: Read the HUNDREDS of posts on the gentoo forums about this.

          The fact of the matter is that portage is plenty fast. Any speed boosts given to the actual emerge program set would be negligable because of the sheer amount of time dedicated to compiling.

          More Advice: Stop trolling.

          When you say that "Portage was a good idea, and is a HORRIBLE implementation" you really need to enumerate WHY it's a horrible implementation.
          Take this common troll as an example.
          Example 1: Windows is a HORRIBLE OS.
          Example 2: Windows is a HORRIBLE OS because being locked into the choices Microsoft made in my "interests" are usually counter-productive.

          See the difference? Example 1, while in many people's oppinion is valid, leaves people wondering why Windows is horrible. Example 2 gives anybody reading specific evidence and also allows anybody that wants to defend the point areas to do so.

          I love the way that gentoo handles packages. I, admitingly, have a BSD bias, but it still allows my system to be what I want.
          The feature set is anything but 'insane,' but once again, I have no idea why you think so, so I can't exactly defend that against any reasons you have.

I'd be extremely interested to see a G5 Xserve entered into that mix, although you'd clearly have to add some unnecessary doo-dads to the Mac to bring the price over $4000 (even with hardware RAID and the inability to drop below an 80GB HD to the 18GB like the Dell has, I could only bring a single processor Xserve up to $3500).

    "In this competition they will be allowing a community of experts in each OS to tweak their configurations to ensure maximum performance."

    I can see it now, teams of KDE and GNOME developers going head to head to see who can come up with the best color scheme, antialiased fonts, and 'Are you sure you want to delete this?' dialog box. Followed by Round 2, where each group has to compile something built for the other camp's desktop, whoever can fight through the dependencies quicker wins!

    Lord Linus, save us from OSNews.

    Will they let you tweak Hyper Threading?

    It'll be interesting to see how many people turn Hyper Threading OFF when doing some tests. I found that my database was 212% FASTER for read operations after I turned Hyper Threading off on the 2650.

      If you enable HT, you are cutting your L3 cache in half per "processor." So your 2.5Ghz Xeon with 512k cache turns into two 2.5ghz chips with 256k each.

      We have deployed a few 6650s here, these are Quad Xeons with 1 meg of cache, and it's amazing to look at top reporting 8 procs. But it didn't take long before we saw the same thing you have.

      But it depends on your usage patterns too. If you're serving a lot of small requests - that run very quickly - HT may not be a bad idea. OTOH, running fewer and larger requests would certainly benefit from disabling HT.

      The reason is that database servers can take advantage of large cache sizes more than most apps. They can move a lot of the dataset near the proc and cut down on query times dramatically. Less cache, more RAM accesses, slower queries.

      About a year ago Dell was recommending that HT be disabled for better performance. Not sure if that is still the case today.

        Interesting. That's not the reason for disabling HyperThreading that I've heard. I often hear people say it should be disabled unless you have a scheduler that supports HyperThreading well. There are lots of opportunities to go wrong when scheduling tasks on HT-enabled CPUs.

        For example, if you have one real processor and are running a high-priority task and a low-priority task, the low-priority task will get 50% of the processor time with a non-HT aware scheduler, since it says "well, I've got this processor free, so I might as well use it" when that's not really true. This problem is discussed more here [kerneltrap.org].

        Similarly, if you've got several high-performance tasks and several real processors, you want to spread them out across as many real processors as possible to maximize parallelism.

    This contest is blatantly set up so that Gentoo, the obvious victor in a fair benchmarking contest, cannot win.

    They are only allowing three days to set up the OS, everyone knows that you can't get gentoo installed, much less customized in that time.

    "Open source" has taken on a whole new meaning since Hustler got involved...

  • These are closer to value server platform...
    2 Procs - comodity, lets see how the various distros do on 16-64 way servers
    2 GB RAM ? why so limiting - lets get this up to 64 GB - or more

    The disk system might not be too bad - but hardware Raid 5 would be more realistic

    Of course what they are going to do is figure out which distro runs a FPS with the highest frame rate

    So, after we're done with the $4300 machine (which, arguably, is cool because you see these OSes at the top of their game), how about a benchmark that is the antithesis of this? What can all the "experts" do given a $430 machine? (Of course, a benchmark against Windows would be in order... and the price of whatever version of Windows is running should be included)

    If one of the reasons to run the benchmark is to show people how great F/OSS is, "round 2" seems like a natural. After all, don't we all know so
