A few things.  That benchmark is about six months old and will be over
an year old by the time Fedora 16 gets released.  There has been a lot
of development happening in between including performance improvements. 
FESCo has a criteria for including Btrfs by default and if there isn't a
proper fsck, error handling etc, Fedora will postpone the move similar
to what happened with systemd in Fedora 14.   I am not sure that website
has any history of publishing good benchmarks and we will have to take
into account as well.
