Hello,

I'm trying to use emacs org-mode to keep my bookmarks (using the
org-annotation-helper.el method). I find this really great, except performance
issues.

My .org file contains ~5000 entries, organized in a tree like this:

#+DRAWERS: MYDATA

** net
*** www
**** [[http://www.w3.org/][W3C - The World Wide Web Consortium]]
:MYDATA: 
  :Entered:   [2000-03-06 10:29:04]
  :LastVisit: [2000-08-31 16:32:15]
:END:

Some optional text

:AEDATA: 
  :Entered:   [2000-03-06 10:29:49]
  :LastVisit: [2001-10-08 15:37:09]
:END:

The problem is that with the drawers activated, it's *very* slow. Cycling the
visibility mode takes more than 10 seconds.
If I remove the drawers configuration line (#+DRAWERS: MYDATA), speed comes back
to reasonable levels, but obviously I lose the drawer effect.

Is there a solution to improve the speed and using the drawers ?

Thanks in advance.

I wonder if this happens with logbook drawers.  I also wonder if it
affects the speed of meta shift up and down (i.e. moving subtrees up
or down).

Hi Al,

first of all, I cannot reproduce the fact that drawers have such
a major influence on time, wit a test file that I created to
be similar to what you describe.

There is a way to speed up drawer handling, by using text properties
instead of overlays.  How have some vague plans to do this, but  
nothing concrete or soon.

It might, but I don't think so

Thanks for your answer, if you want I can send you an example file (160kB
compressed).

There are also performance problems just when moving the cursor up and down.

Just for the records, I'm using emacs-gtk 22.3.1 and org-mode 6.27a-1 on a
debian linux setup.

Hi Al,

I think I have now been able to speed this up a lot.  There is
still a strange delay when you switch to CHILDREN view in
your Bookmark entry *for the first time*.  However, after that
things seem to be much faster.  I have no idea where this
initial delay comes from, it might have to do with the way
Emacs handles character properties internally.

Anyway, even the first time you use CHILDREN view is now much
faster than it used to be.

Please let me know if this solves the issue for you.

- Carsten

P.S.  Unfortunatey, I cannot fix the performance issues
regarding vertical cursor motion, this is in the guts of
Emacs.  `C-c C-f' and `C-c C-b' do help a bit...

Hello Carsten,

I'm just back from holidays and I've checked with current git version
6.29 trans (instead of the 6.27a I was using). It is much faster, even
for vertical cursor motion. Thank you very much for your work.

It is funny that outline-previous-visible-heading is faster than
previous-line when the previous subtree is folded.  I wonder if Emacs
searches for bol when it should be searching for visible text first,
then bol, or something.

In any case, thanks for the speedups.

WHen Emacs does `previous-line', it does line by line, moving
on when the line is invisible. C-c C-b search headlines by regexp
and check only the headlines for visibilitiy.
