Phoronix: Btrfs Is Not Yet The Performance King

With the release this week of Fedora 11 Preview, which incorporates install-time support for the Btrfs file-system into Red Hat's Anaconda installer, we have now delivered our first set of benchmark results for this next-generation Linux file-system. Through a horde of disk tests we have looked at the Btrfs file-system performance and compared it to that of EXT3, EXT4, and XFS. While Btrfs does perform well in some areas, it is not yet the performance king for Linux file-systems. As our results show, in some tests it even has a hard time competing with the incremental EXT4 file-system.
