Something completely different - Documentation/filesystems/ext4:

  - When comparing performance with other filesystems, remember that
    ext3/4 by default offers higher data integrity guarantees than most.
    So when comparing with a metadata-only journalling filesystem, such
    as ext3, use `mount -o data=writeback'.  And you might as well use
       ^^^^
    `mount -o nobh' too along with it.  Making the journal larger than
    the mke2fs default often helps performance with metadata-intensive
    workloads.

Anything _but_ ext3 here?
