    oh boohuuu. How many sites out there test hardware or games on more than one system?

    Doing a comparism on one piece of hardware is fine. Comparing something completly different to that results and then conclude that the test was bogus is not.

    I can't do a clear comparison, but there is no way possible that my 8.04 machine should be anywhere close to a T60, I have done enough cross architecture testing in the past to know this. The values shouldn't be anywhere this close and since the T60 performs right where it should to a 1.7 pentium 4 first gen in the 7.04 and 7.10 tests, I would have to believe there is another problem.

    Besides Phoronix test is instant fail as they tested only one fucking machine to do a OS speed comparison, that is called amateur.

    instant fail, you can't compare like that. Compare different ubuntu versions on your box.

    OK I just ran a quick Encode-mp3 test on my system which runs Ubuntu 8.04 and my results do not jive with Phoronix's.

    My system is a 1.7GHz Pentium 4(first generation) with 768MB(RIMM) memory, so should be a little less than twice as slow as a T60 dual 1.83GHz Pentium M cores and 1GB memory. A Single core Pentium M 1.83GHz would perform as well as a 3 GHz Pentium 4 first generation, So since lame doesn't use multithreading a comparison can be made as the second processor in the T60 will remain mostly unused, and still the T60 should be about 44% faster. (my hardrive is very old 10 Gig drive, so the T60's should be the same or better)

    My results were 123.14s compared, to 116.67s on the T60, so yes my system is just slightly slower than the T60, which is only about 5% faster, where it should be about 44% faster (which is what you see the T60 do on the test under 7.04).

    I would also add, it is a really really really bad idea to do a OS version speed comparison, and only use one machine, two different machines is the bare minimum to be able come to any conclusion and write an article, and I would do probably five machines with different architectures, also changing system memory amounts to see any differences as well.

    This may have something to do with the fact that your Ubuntu 8.10 may be your first partition... Could it?

    I'll run a few tests again (unfortunately i don't have "more than 100 hours" to run all the tests) and post the graphics/results here later this day. My T60 is the 2007-FVG Model.

    All i can tell you for now is that i get up to two times better results at all your audio-encoding tests -actually very close to Ubuntu 7.04/7.10

    trooper09: I can assure you both cores were enabled and that cpuinfo reported both cores.

    I don't know... I am sorry if I am doubtful, but I typically use this command to ensure I have both core enabled:
    Code:
    cat /proc/cpuinfo

    There is a huge difference between supported and enabled.

    Must be because of language support
