    If you have an application that needs to pull lots of data really fast (using
    directio) for long periods of time, you really should be using XFS. We tested
    a load of filesystems where i am working and only xfs got the throuput we
    needed (~430MB/s off a raid array) whereas the best ext3 and reiser (might
    not have been reiser4 though) could get was about 350MB/s
