My measurements (which I posted a few minutes ago) indicate that Emacs
25 is about twice slower than Emacs 23.3. So the above means the
comment-cache branch brings the performance almost back to its Emacs
23 level. Which is a Good Thing, I think.

To me, it's very important, because I bump into the slow situations
way too much.
