Btrfs Is Not Yet the Performance King

Posted by timothy on from the happy-churning dept.

Ashmash writes "Benchmarks of the Btrfs filesystem have been published by Phoronix that compare it to the XFS, EXT3, and EXT4 file-systems. In the end they conclude that this next-generation Linux filesystem is not yet the performance king. In a great number of the tests, the EXT4 filesystem that was designed to be an interim step to Btrfs actually performs much better than the unstable Btrfs, albeit Btrfs still has more advanced features. Fedora 11 even took longer to boot when using Btrfs than EXT3 or EXT4."

    I don't care which filesystem is fastest. Kcryptd is the bottleneck on my system, so it really doesn't matter how fast the filessytem is. I want to know which filesystem is the most robust. What filesystem is least likely to lose data?

      I think it's important to keep in mind that it is the GPL that is incompatible with other free licenses, not the other way around.

      You're right, Sun had no idea their new license would be incompatible with Linux because they wanted to be compatible instead of doing the slimy thing and trying to make it be a selling point over using Linux, which everyone was doing. Alas. for them RMS and Linus travelled back in time and created/used the GPL just to thwart poor Sun.
