LXer: Btrfs Is Not Yet The Performance King


Published at LXer:

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.

I think this benchmark is BS. They didn't even include JFS (winner of many previous benchmarks) or Reiser4, they didn't mention the insane behavior of ext4 by default (probably still on during this test to make it appear that ext4 is better), and a better part of the test was NOT testing filesystem performance at all.
