Maybe my problem is not related to slow folding/unfolding behavior that you are getting, but if I set the org-src-tab-acts-natively variable to t the folding/unfolding of headlines becomes very slow for me.
In fact, I was thinking that I had the problem described here, but I just isolated the cause and in my case it was the org-src-tab-acts-natively variable that I had set to t in my .emacs file. -- Darlan At Tue, 7 Sep 2010 06:05:54 -1000, "Thomas S.
