In general, ext3 tends to move the disk head all over the platter during benchmark runs while Btrfs and XFS do better. Chris noted that better writeback clustering in the virtual memory subsystem would help ext3.
So presumably ext4, which adds delayed and multiblock allocation to ext3 will improve things. Also, IIRC there was some discussion about moving these features into the VFS layer. That being said, perhaps ext4 development is slowing down now that Sun went and bought clusterfs.
