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
