Graphs from <http://btrfs.boxacle.net/repository/raid/2.6.35-rc5/2.6.35- rc5/2.6.35-rc5.html>. 75 "votes", attached. Rankings: 1. jfs 2. xfs-nobarrier 3. ext4 3. ext4-nobarrier (tie) 5. xfs 6. ext3 7. ext3-barrier 8. btrfs-nocow 9. btrfs Excluding the variants which as unsafe because they do not use barriers: 1. jfs 2. ext4 3. xfs 4. ext3-barrier 5. btrfs-nocow 6. btrfs I'm slightly surprised by the results. It's possible it was slightly weighted toward JFS because of the "%CPU" and "Ops/%CPU" metrics, which I don't think matter too much. I'd love to see data for 2.6.32 (Squeeze) and 2.6.38 (Wheezy/Sid). -- Boyd Stephen Smith Jr. ,= ,-_-. =. b...@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
