Actually, I would suspect it's more of a problem for follow-mode
than org-mode, because follow-mode needs to keep the different
windows in sync. For this, it adds a function to
`post-command-hook', which means it's run after every key press.
It's not inconceivable that `follow-mode' does something that is
extra time-consuming in an Org buffer. To find out what that might
be, you could try the Elisp profiler that comes with Emacs. See
the section "Profiling" in the Elisp manual for details.
Once you've found out which function(s) consume so much time, it
might be possible to ask in here or on emacs-devel what exactly is
causing the problem and whether there's a way around it.
