Thanks for these details. I can report similar experiences with large files. As far as I understand, large org-mode buffers are slow because there are many overlays, which (unlike text properties), don't scale well: (info "(elisp) Overlays") This is right now an inescapable limitation of org-mode, since outline-mode relies on overlays. There was brief talk on emacs-dev of rewriting text-properties so that outline-mode could use them instead of overlays, but I do not believe the proposal was pursued further: http://permalink.gmane.org/gmane.emacs.devel/131304 Best, Matt
