    Default Btrfs Did Regress Hard In The Linux 2.6.35 Kernel

    Phoronix: Btrfs Did Regress Hard In The Linux 2.6.35 Kernel

    This morning we published benchmarks of ZFS, EXT4, and Btrfs when running these three popular file-systems off a high-performance OCZ Vertex 2 solid-state drive and also a 7200RPM notebook hard drive. To a fair amount of surprise, the EXT4 file-system ended up beating out Btrfs on the SSD in a number of tests, which was a change from our tests when using the EXT4/Btrfs modules on previous kernels. It was even more surprising since Btrfs has an SSD-optimized mode where as EXT4 does not. However, it turns out this is part of a major performance regression for this file-system in the Linux 2.6.35 kernel...

    That's the problem with Ubuntu. They are quick at jumping on new technology, before it is mature. Fedora is also always on the bleeding edge of technology, but that guys are doing it right. They are fixing stuff instead of only complaining to upstream.

    Fedora is on the forefront of creation and fushing forward.

    Ubuntu is a compilation of what Canonical thinks is the creme-de-la-creme of the current Linux ecosystem and pressents that to the enduser in a way that endusers can experience today, while Fedora is here for the future.

    If Ubuntu was just being Fedora then there was no need for Ubuntu.

    Default BTRFS dead in the water

    Now that Oracle is pushing proprietary Solaris and ZFS, they dropped BTRFS dead, and no other company is putting man-power to improving it. Just look at how quiet the mailing list has got. Very few patches.

    But you can say similar things of MickeySoft

    When there are regressions in Linux they get fixed

    Linux is the kernel. If there's no kfreebsd.org, kapple.org, kwindows.org, kslowlaris.org then it's hard to say how the other kernel development looks like. When Ubuntu or some distro regresses then it's a different thing. Btw. there are no more stable releases, maybe except lts kernels.

    It seems you're talking bull:

    http://git.kernel.org/?p=linux/kerne...git;a=shortlog

    Could you point to zfs and solaris mailing list to have some comparison?

    No, LTS kernels are still 2.6 series. The latest stable kernel (2.4.37.9) was released in February of this year.

    I'm sorry, but I don't understand you. Why 2.6 series aren't stable in your opinion? I wouldn't even touch 2.4 series.
