hi,
from the reading I've done there is that first conclusion - 
it may different a lot with each FS - people theorize. I 
wonder if anybody put them into practice.
I wondered if btrfs/xfs was any good, etx4 in current 
kernels does not support "packed_meta_blocks" yet. Some 
hands-on experience.
thanks
