Sometimes Emacs will lock up for several seconds. For instance, to move from the level one heading "* Other" to "* Closed issues" when the outline is folded takes over three seconds: --8<---------------cut here---------------start------------->8--- next-line 1 3.015289 3.015289 --8<---------------cut here---------------end--------------->8--- In my experience, the maximum workable size of org files is around 10,000 lines. Beyond that, Emacs starts to spin its wheels. Do others have the same experience? If so, does anyone have any tips on how to diagnose this further?
