>From what I've seen in fs comparisons, btrfs is the slowest fs out there ( http://www.ilsistemista.net/index.php/linux-a-unix/6-linux-filesystems-benchmarked-ext3-vs-ext4-vs-xfs-vs-btrfs.html as well as others). Does it make sense that that is going to be the fs of choice for F16? Am I missing something very obvious? Kevin
