"moderate speeds up"?

Looks like a big win to me. Admittedly it's already a pretty fast
operation, but script it and repeat it a million times, and that will
matter a lot more.

I guess the "--raw" diff part means that you are hiding the time to
make a real diff, which would otherwise swamp everything else. Even
so, this looks like a good improvement.
