ext[23] reserves a chunk of filesystem space for the superuser.

ext3 is a data journalling filesystem.  That's a feature which
has a cost.  But if you mount with `-o data=writeback' it will
run in metadata-only journalling mode.  Which is, I suggest,
a more appropriate way of comparing with other metadata-journalling
filesystems.
