Double-buffering decreases the number of display updates, so it hardly
can be the cause of this.
As we've discussed with Stefan, the implementation is likely the reason.

It doesn't scroll much faster than with the value of 0 (that already
scrolls fast enough).
It doesn't flicker while scrolling because it simply shows unfontified
screenfuls of code. Which is unacceptable for default behavior. And I'd
hesitate to recommend it to anyone even to deal with performance problems.
It *does* flicker afterwards (e.g. 0.5 sec after I depress C-v), because
that's what deferred jit-lock does: it applies syntax highlighting with
a delay. So I type, wait 0.5sec, and syntax highlighting arrives. It's a
less-aggravating kind of flicker because of its laid-back pace, but I
still wouldn't call it acceptable user experience.
