they tested crap. |

As I wrote in the other mail. XFS and reiserfs turn on barriers by default, |
22 |
ext3 turns them off. |

With barriers on for ext3 it looses 30%(!). reiserfs and xfs don't suffer as |
24 |
much, but suffer they do. So if the test did not turn on or off barriers for |
25 |
all fs who support them, ext3 had an unfair advantage. |

And you want barriers. |
