About 1500 slides (350 actual frames with overlays) for a 20 hours course.
LuaTeX + opentype fonts makes it even slower. Some complex slides with
animate algorithms (mergesort, ford fulkerson, stuff like that)
Ok, I can split it in lectures (albeit that's not so simple to use
\lectureonly without
breaking toc). I can use the externalize library. Etc.

Anyway, what's bother me on the long run is that it is only slides. The
browser is able
to render / typeset the text and graphics by itself. No need to resort to
such complex
compilation (there is MathJax, and stuff like Raphael.js and jQuery that
could do the job).
The more powerful your tool is (luatex, opentype fonts etc) the more you
lose
time with details.
