It is from 2.6.34-rc3 (unpatched). It compares ext3 ext4 ext4-nobarrier, btrfs, btrfs-nocow, xfs and jfs on a software raid setup with a decent spindle count. http://btrfs.boxacle.net/repository/raid/2010-04-14_2004/2.6.34-rc3/2.6.34-rc3.html As we know touring barriers off helps a lot with ext4 on this machine. I think Steve Pratt send some notification to the btrfs folks. Feel free to point others at this data. A history from this setup can be found here: (mostly btrfs related data) http://btrfs.boxacle.net/repository/raid/history/History.html I hope to be do these large data set runs once in every major kernel revision life cycle.
