Or > just in Org buffers? No problem, with the same files, if I put them in `text-mode'. So, it becomes apparent with Org. Remember I told there were similar speed problems with some Gnus buffer, but I haven't tested them again. > If the latter, perhaps your Org files are special in some way, because > the ones I tried don't show any slowdown I could sense. They aren't special, for two reasons: - They're not mine; they're public Org files taken from the Worg project ("Wiki Org"). - They work perfectly in Emacs rev 114715: no performance degradation whatsoever. For the sake of clarity, I've redone a comparison of the two different Emacs (r114715 and the recent r115235) on the same two Org files: - ChangeLog.org (1,156 bytes) http://code.ohloh.net/file?fid=s6NzuuiKK0Nlga9EF-Vh8KzVXiw&cid=SNfK_pTfQmo&s=&fp=19410&mp=&projSelected=true#L0 - org-faq.org (164,174 bytes) http://code.ohloh.net/file?fid=Jk4U4mwQtJT_5LfYpl3sBLhj42s&cid=SNfK_pTfQmo&s=&fp=19410&mp=&projSelected=true#L0 Just look at the CPU usage, and see how the cursor moves slowly -- while I press on the arrows at the same speed in both configs. See http://screencast.com/t/oHIPTP0eAW. For the records, my .emacs is really tiny, as you can see: --8<---------------cut here---------------start------------->8--- ;; highlight trailing whitespaces in all modes (setq-default show-trailing-whitespace t) (setq org-ellipsis " \u25B7") ; string ;; title bar display of visible frames (setq frame-title-format (format "Emacs %s rev:%s of %s PID:%d" ;; (capitalize (symbol-name system-type)) emacs-version (ignore-errors (replace-regexp-in-string " .*" "" emacs-bzr-version)) (format-time-string "%Y-%m-%d" emacs-build-time) (emacs-pid))) --8<---------------cut here---------------end--------------->8--- Please don't tell me nobody can reproduce this problem!?
