If I start an emacs -q, open the header in question, M->, M-v, emacs
takes a bit more than 2 minutes to respond. Scrolling in the fontified
area is smooth after this initial work. I see similar timings for
emacs -q -nw.
After M-x font-lock-mode scrolling is essentially instantaneous in
both those configurations.
I suspect hardware doesn't have much to do with this issue, but for
what it's worth I'm running on a core 2 duo.
> FWIW, it's not particularly slow on my 6.5-year old hardware. Much
faster than the previous data point.
Interesting. What version of emacs and cc-mode are you using?
