Hi!

You could try the patch, reshuffle your disk and easily might get
another 2x speedup. Situation is like this:

FSCKspeed SPACEefficiency NORMALspeed
normal ext2 low good high
ext2 with bs=4K high bad high
ext2+my diff high good lower
(and, probably)
ext2+my+bs=4K veryhigh bad lower

Setting bs=4K is completely orthogonal to my patch, they should be
pretty efficient together.
