[opensuse-factory] Disk transaction performance - Phoronix benchmarking
Hi all. Phoronix has run distribution comparison [1]. I´m just wondering why disk transaction performance has Ubuntu 10.04 faster than openSUSE 11.3 RC1, when both distros uses an ext4 file system. Does openSUSE have enabled any barriers again, as was in openSUSE 11.1? http://www.phoronix.com/scan.php?page=article&item=linux_2010_fiveway&num=1 Thanks. -- S pozdravom / Best regards, Rasto -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

The default changed upstream and openSUSE only was ahead of its time. Benchmarks are only one side of the story, functionality and data integrity another.

Phoronix benchmarks are BS, I hope you are not taking that thing seriously do you ? -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

So let's have a blog post or news story on news.opensuse.org to explain our position! The right thing is not to ignore the benchmarks, but to educate people so we don't look bad with no reason.

Would you care to post what you find BS about them? Most of the benchmarks are done by using real life applications doing their tasks unlike most other BS benchmarks that live off of synthetic benchmarks which have no relevance in real life applications. Of course if you know of a flaw please feel free to contribute. Patches are welcome.

I don't take them as the ultimate truth, but neither as BS.

Meanwhile, why doesn't any of you comment on it? Stephan has hinted on functionality and data integrity; perhaps we are using different defaults than others, but knowing what those could be would be nice. Perhaps it is something as simple as the comparison being run against a beta with debug capabilities enabled :-? - -- Cheers / Saludos, Carlos E. R.

No matter whether you might think the benchmarks are BS or not - I cannot answer that technically - this is one of our problems - perception... So, we need to either publicly demonstrate with repeatable test cases that the benchmarks are indeed problematic or find why we are not getting the same results if indeed it is a valid benchmark. I met Michael at LinuxTag and he is a sensible guy who has no bias against openSUSE. I explained in detail why I openSUSE is my preferred distro with some real world examples of success. He was floored when I mentioned the uptimes of some my client's servers on SL*/openSUSE. - years, not months... We have a great distro, but often we have difficulty to explain to the larger public our technical excellence ;) Just my 0.02 $currency Peter -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

Thanks.
And again, Ubuntu 10.04 has faster disk transaction performance with older kernel than final 11.3. Can anyone explain why? http://www.phoronix.com/scan.php?page=article&item=opensuse_113_benchmarks&num=3 Thanks. -- S pozdravom / Best regards, Rasto -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
