Yup, that's exactly what I'm seeing. Pick two books, do a metadata update through the individual update screen and it's poof, poof, done. Do it with the bulk update screen and it's wait...wait....wait....done. Far more than twice as long as a single update.
It's database size related, too; the effect is a lot less if your library is smaller.
