If you break a big file system into smaller partitions, you'll get a
speed up in the mount time. However, The mount speed appears to be
pretty linear, although much faster than a comparable JFFS2 file system.
Thus 2 64 MB partitions that are full will take about 5 seconds each to
mount.

Of course, you don't really want your file systems full, since you'll
have no spares when you need to write a file, but I'm just talking about
theoretical limits.
