I've noticed that:

 - with x86-64 Fedora 15 DVD install images:
   - du -sh <ROOT VOLUME> was 36 GB
   - btrfs df | grep -i data have shown over 40 GB used
 - without
   - du -sh <ROOT VOLUME> is 34 GB
   - btrfs df | grep -i data have shown less then 34 GB used

It seems that iso files are considered compressable while they may not be (=
and penalty is severe - 3x).
