See my separate timing numbers, although I bet that Chris can give even
better ones..
Chris, try applying my patch, and then inside the KDE repo you have, do
git index-pack --paranoid --stdin --fix-thin new.pack < ~/git/.git/objects/pack/pack-*.pack
(ie index the objects of the *git* repository, not the KDE one). That
should approximate doing a fair-sized "git pull" - getting new objects. Do
it with and without --paranoid, and time it.
I bet that what I see as a 7% slowdown will be much bigger for you, just
because the negative lookups will be all that much more expensive when you
have tons of objects.
