I asked Keith if he could do xfs nobarrier runs as well.

If there are ext4 nobarrier runs "winning" it seems only fair.  :)

At long last here is a good data set for filesystem comparison.  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. 


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


I hope to be do these large data set runs once in every major kernel
revision life cycle.
