Have you tried doing it (scrolling through the buffer) _twice_?

On debian, paging through the buffer the first time through is pretty
slow, presumably because it's rendering tons of new characters on every
page, but if I go back and do it again it's very fast (not perceptibly
different than pages full of normal text).  I assume there must be a
fair-amount of caching going on...
