If you can't reproduce, let me know what else I should check.
SLIME does some font-locking; you could try to set slime-highlight-suppressed-forms to nil before loading SLIME.
You could also byte-compile almost everything, to avoid consing during macro expansion.
I usually leave scroll-conservatively to 0, so I can't say what would qualify a smooth scrolling. If I set scroll-conservatively to 1 and SLIME isn't loaded at all, scrolling is also not entirely smooth and stops for bit after 3 pages or so. If SLIME is loaded it stops more frequently ca. after 1 page. Displaying the REPL buffer or not doesn't seem to make a difference here.
