you'll need to debug why it is taking so long on your machine.

I'm not talking about C-v. I'm talking about scrolling one line at a time.

I use this in my .emacs

(setq scroll-preserve-screen-position 'always
      scroll-conservatively most-positive-fixnum
      scroll-step 0)

because I *hate* recentering during scroll.

If you try the above setup with and without the new backend, you'll
see the difference, I think.

I don't see a significant difference, certainly nothing to justify language like "unusable" and "unbearable" that has been used on this thread. Both recenter occasionally when the redisplay cannot keep up with key repeat, with the new font backend it may happen more frequently, but that is not surprising for new development code that has not yet settled down, so noone has tried to optimize it yet.
