    Two major problems with this test:

    1) It used a pre-release OS (FreeBSD 8.0) which can have a significant impact on performance.

    2) FreeBSD 7.2/8.0 both used Gcc 4.2.1 vs Ubuntu using 4.4.1, which can make as much as a 20% difference (4.4.1 faster) in performance according to the GCC developers:
    http://vmakarov.fedorapeople.org/spec/comparison32.html

    You will notice that compile time and run time for heavily computational tasks are better in Ubuntu, which is as expected with the GCC change.

    While it may be a fair argument, that FreeBSD 8.0 shouldn't include Gcc 4.2.1, it isn't a fair statement to make that this test proves FreeBSD is slower. Frankly, I don't know how well it would perform if the test was done on a level playing field (same hardware, same compiler) but testing with these kind of low level software differences (gcc) from a 3rd party isn't a fair test.

    AFAIK Ubuntu prerelase too. So the test is valid.

    But that does not change the fact that FreeBSD looses even when only comparing releases. So either way, FreeBSD looses.
    Ubuntu pre-release doesn't have debug flags on, so the test is invalid.

    I'll agree on the full release stuff, and personally rarely touch FreeBSD these days, but do bear in mind that it's been a year and a half since FreeBSD was released. Phoronix would have done better to compare FreeBSD7 to Ubuntu 8.10 or even 8.04 given the pace of change in both OSs.

    I'm looking forward to it.

    yeah, FreeBSD the truck. More like, FreeBSD the broken bicycle.
    Uhm, that's 2006, and FreeBSD 6.x. You clearly don't know much about FreeBSD.
    FreeBSD went through huge changes in the design in 5.x, which made it actually slower than 4.x, AFAIR. But, since then it was improved constantly, with each release.

    This is a more recent benchmark, targeted on the SMP code:
    http://people.freebsd.org/~kris/scaling/dfly.html

    It is mostly a benchmark of FreeBSD versions and DragonflyBSD, but Linux kernels were used too. Now, that particular Linux kernel is rather old, so I expect some changes in newer releases, but still I hope it will shut you up for now.

    I honestly expect better results from 8.0 RELEASE, compared to 7.2 RELEASE, knowing how careful the guys from FreeBSD are with the releases.

    I don't think FreeBSD should be compared with Ubuntu. It's not fair for Linux since Ubuntu is a desktop distro, not the first choice for servers and workstations.

    It doesn't show FreeBSD is slower than Linux, all it is is utterly pointless. RCs of most OSs (Ubuntu is a bit of an exception here rather than the norm) have so many debug flags and stuff set which use so much CPU time that it's stupid to benchmark it.

    Well, that's no excuse. The benchmark is still completely useless. I *do* expect of them to do another run after both OSes are released.
