Upgrading is certainly worth trying.  Any obstacles agains doing that?


It should be no need to reformat the files. If it can be fast, it
should be fast, and if it get slow, this must mean that something
is wrong - either in Emacs or in Org.

Sometimes too many overlays can cause these problems.  Maybe you can try
these when it is slow:

1. Try to close all org-buffers before making the agenda.
   Does this help, maybe already on the first creation of
   the agenda, but certainly on the second?

2. Another try could be to cycle all Org buffer through
   visibility (three times S-TAB in each buffer).  Does that
   make a difference?

Mind you, this is not for everyday operations, but to help us
find out what is wrong.
