    An idea on where the problem possibly lays. Some posters have reported no real differences on their T60's across Ubunutu versions, and some have posted speeds that don't correlate to Phoronix's on 8.04 8.10 on T60's. But all these T60's seem to be Merom Core 2 Duo's, not Yonah Core Duo's.

    I propose that the problem might lay in some Ubuntu's versions interaction with the Yonah Core Duo feature set, or possibly with chipsets, though I don't know if the motherboards are different, they very well could be the same.

    I do remember some kind of problem I saw a couple years ago, with I think Mandriva, on a Core Duo, which was not related to EIST, where both cores reported as up and working, but one core ran incredibly slow, this would effect non-multi-threaded tasks more than others, if they were running only on that core. No problems in this regard when I put Debian back on it instead.

    Way to go, to everyone who contributed to the creation of the Phoronix Test Suite and to these benchmarks of using that test suite on various Ubuntu releases. Thank you!

    I'm happy that future releases of Ubuntu (and probably other Linux) are going to get noticeably faster, and in large part thanks to your work. Keep it up!

    It's a real bitch having to write yourself up on disciplinary issues when that happens.

    Also, concerns about destructive background processes should be addressed - I know on at least one laptop that the indexer was slowing down my system on 7.10 and 8.04. This might best be disabled on every test since it's potentially broken depending on your system.

    Try a few different hardware systems, and try 64 bit linux as well! It really annoys me to see such a grandiose claim being made without a proper investigation on a site I really respect. Thanks for the hard work, but you can do better!

    Note that I didn't make any definitive claims about Ubuntu getting slower but more along the lines of provided some thoughts on what I had experienced, posed some questions, didn't attempt to make any blanket claims, and I didn't start pointing any fingers around.

    Though reading the feedback though from here and on the Ubuntu Forums in particular, others definitely agree that there are areas within Ubuntu that could be better optimized for performance. Going out of this hopefully the open-source community will pay better attention to performance testing.

    As mentioned several times now, other systems and distributions are in the process of being tested, but alas with limited staff (essentially just me) and very limited resources (I can assure you Phoronix Media is no cash cow), it's not feisable to test everything out there.

    Flawed approach?

    i just uploaded my audio-encoding results.
    -> http://global.phoronix-test-suite.co...443-32506-2318

    they are twice as fast as the ones presented on the web site. There is something terribly wrong with the intrepid installation/configuration of the (phoronix) test machine. Or the test has quite a few ugly bugs.

    How many readers judge hardware based on ONE review? I hope you get the point.

    If not then the results should be reproducible.

    Encoded 52.6MB WAV to MP3 on one machine with one version of lame (3.98.2):

    31.7 sec. on Feisty
    31.1 sec. on Hardy
    30.9 sec. on Intrepid RC

    That doesn't correlate with Phoronix' encoding time increase of ~100% from Feisty to Intrepid and I haven't seen any other results that do.

    I'm not a fanboy - I'd just like to see benchmarks that are worth reading and I know that's what Phoronix want too.

    @energyman :

    Have you ever heard the term "proof of plausibility".

    they stopped using xp or doing comparisms a long time ago - and when they test hardware, they only change ONE (!) piece at a time.

    I didn't say the test was bogus, just that there must be something up on the t60 under ubuntu 8.04+, other than newer ubuntu just being naturally slower.

    I'm not a big ubuntu user and this older machine is the only one I have with it installed, and I don't really have the time to put on 7.04, though if I was running a benchmarking site that wanted to be taken seriously I probably would. It used to have debian lenny on it, but I decided I would take a look at ubuntu, I didn't notice any real performance difference between the two.

    There are many sites that are amateur benchmarking sites, it's unfortunate that Phoronix seems to be one of them.

    Yes most serious hardware benchmarking sites, for example for gamers, benchmark games on a huge host of hardware to do comparisons. There were comparisons done for example on gaming on XP versus Vista, and serious benchmarking sites compared across multiple machines and architectures and memory configurations, it just goes without saying. I don't see how this is so hard, anyone in IT usually has multiple machines they can test on, just in their own personal possession, let alone if they are running a benchmarking site. I have about 10 different machines in my house alone, most of which I got cheap from clients or jobs or bought used. So testing on at least two machines to weed out a possible hardware specific problems is a no brainer.
