[Fwd: Benchmarking data from a raid machine 2.6.34-rc3]

FYI...

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.

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)

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

Thanks,

Do you have a link to the hardware specs used in the testing Eric?

Thanks.

There are machine specs at http://btrfs.boxacle.net/ but I don't know for -sure- that he's testing the exact same setup now.

I assume so, though. (I shoulda included that top URL in the message)
