Nope. C-p and C-n appears to be equally fast.

What I notice however, is that if I unfold all the headlines displayed
on the screen, the navigation is perfectly normal.

The cursor movement only stutter when the headlines are folded (whatever
the headline level).


Finally, I tried `outline-next-visible-heading' and it turns out to works like a charm.


Hope that helps
