For whatever reason, I've noticed that there are:
- 96 calls for 32 files in my org-agenda-files
- 99 calls for 33 files in my org-agenda-files
hence, 3 font-lock-fontify-buffer calls per Org file[1].
Anyway, I now do have found the culprit: the =column-marker= package (which
highlights my columns 78, 79 and 80 of text), loaded in my .emacs file by this
snippet):
#+begin_src emacs-lisp
;; highlight columns 78 to 80 in some modes
(when (require 'column-marker)
(dolist (hook '(emacs-lisp-mode-hook
cperl-mode-hook
shell-mode-hook
text-mode-hook
change-log-mode-hook
makefile-mode-hook
message-mode-hook
texinfo-mode-hook))
(add-hook hook (lambda ()
(interactive)
(column-marker-1 78)
(column-marker-2 79)
(column-marker-3 80)))))
#+end_src
It accounts for a bit more than 10 s delay in the total time of my .emacs file
-- which, currently, still calls (org-agenda-list):
- with it, total time is 70s - 73s
- without it, total time is 80s - 84s
The difference is really huge...
Though, such a capability being really nice, do you know some replacement for
this?
Best regards,
Seb
Footnotes:
[1] The offending package highlights 3 columns in the buffer: maybe that's the
factor 3 for every Org file...
