Hi Sebastian
I meant setting org-agenda-show-outline-path to nil.
-----------------------------------------------------
Now the more intersting news.
Reading through my .emacs I found and removed the 2 reasons for the slowness!
1. smooth-scolling.el (from http://www.emacswiki.org/emacs/SmoothScrolling)
The file includes this:
#+BEGIN_SRC emacs-lisp
(defadvice previous-line (after smooth-scroll-down
(&optional arg try-vscroll)
activate)
"Scroll down smoothly if cursor is within `smooth-scroll-margin'
lines of the top of the window."
(and
;; Only scroll down if there is buffer above the start of the window.
(> (window-start) (buffer-end -1))
(let ((lines-from-window-top
(smooth-scroll-lines-from-window-top)))
(and
;; Only scroll down if we're within the top margin
(<= lines-from-window-top smooth-scroll-margin)
;; Only scroll down if we're in the top half of the window
(<= lines-from-window-top
;; N.B. `window-height' includes modeline, so if it returned 21,
;; that would mean exactly 10 lines in the top half and 10 in
;; the bottom. 22 (or any even number) means there's one in the
;; middle. In both cases the following expression will
;; yield 10:
(/ (1- (window-height)) 2))
(save-excursion
(scroll-down
(1+ (- smooth-scroll-margin lines-from-window-top))))))))
(defadvice next-line (after smooth-scroll-up
(&optional arg try-vscroll)
activate)
"Scroll up smoothly if cursor is within `smooth-scroll-margin'
lines of the bottom of the window."
(and
;; Only scroll up if there is buffer below the end of the window.
(< (window-end) (buffer-end 1))
(let ((lines-from-window-bottom
(smooth-scroll-lines-from-window-bottom)))
(and
;; Only scroll up if we're within the bottom margin
(<= lines-from-window-bottom smooth-scroll-margin)
;; Only scroll up if we're in the bottom half of the window.
(<= lines-from-window-bottom
;; See above notes on `window-height'.
(/ (1- (window-height)) 2))
(save-excursion
(scroll-up
(1+ (- smooth-scroll-margin lines-from-window-bottom))))))))
;;;_ + provide
(provide 'smooth-scrolling)
#+END_SRC
2. (add-hook 'org-agenda-mode-hook 'hl-line-mode)
-----------------------------------------------------
Switching off both features brings back immediate scrolling.
I do miss the features of smooth-scrolling and hl-line but it is not worth the
performance penalty.
Thanks to all for considering and helping.
What a relieve to be able to again scroll fast in the agenda ...
Best,
Rainer
