Excellent!

A suggestion: use the filesystem type "auto" instead of ext3.  At boot, your
kernel will pick the appropriate filesystem: ext3 if the fs is capable (already
tuned), or ext2 if not.  Additionally, you can still use recovery discs that
may only support ext2.

Are you certain it's faster?  I don't know much about the particulars of how
ext3 is implemented, but I was under the impression that a slight performance
hit was the tradeoff for journalling.
