Now I think I found something specific. I do open the org-mode file in question with #+STARTUP: showeverything because otherwise it’s slow. Today I discovered org-goto. This presents the buffer in overview mode. So I started the profiler, started org-goto and typed 11 letters in order to jump to a heading. This takes quite some time while my notebooks fan is making noise and Emacs uses 100% cpu according to htop. I did this two times with the same org-mode file: - with Org-mode version 8.3beta (release_8.3beta-1291-gd6e601 @ /home/grfz/src/org-mode/lisp/) on GNU Emacs 25.0.50.4 (i686-pc-linux-gnu, GTK+ Version 3.14.5) of 2015-07-17 on boo - with Org-mode version 8.2.10 (release_8.2.10 @ /usr/local/stow/emacs-snapshot/share/Emacs/25.0.50/lisp/org/) on the same version of Emacs. I do not know how to read these reports, but to me it seems, that most of the cpu cycles are used by org-context, org-end-of-item, org-list-struct and org-list-context. The memory reports do not seem to be of interest but I attach them for the sake of completeness. HTH, Gregor -- -... --- .-. . -.. ..--.. ...-.-
