Flyspell causes severe slowdown when manipulating footnotes

Flyspell causes severe slowdown when manipulating footnotes

I just upgraded to Org 9.6 and I've noticed that having flyspell-mode
turned on causes very large slowdowns when adding or deleting footnotes in
an org file with lots of footnotes (e.g., more than 200, which is common
for the academic articles that I use org for). Any ideas for what might be
causing this?

Most likely cache updates.
Could you please (1) Set org-element--cache-self-verify to nil and see
if things get back to normal; (2) If things are still slow after setting
the variable, please run M-x profiler-start ... M-x profiler-report and
share the data. See https://orgmode.org/list/87ee2nlslt.fsf@localhost.

Thanks Ihor for the response. Unfortunately, setting
org-element--cache-self-verify to nil didn't work. Profile report attached.

Thanks!
I just pushed a slight optimization to the footnote sorting code.
Can you try again using the latest main?

Unrelated to the footnotes mentioned above, but I noticed that Org
starts and kills Ispell all the time.  I see the following messages
repeated over and over when working with Org:

  Starting new Ispell process aspell with american dictionary...done
  ...
  Ispell process killed

For the sake of experiment, I have just tried to export (to HTML) a
subtree that contains nothing in it but a single BibTeX source block.
Sure enough, Org started and killed a new Ispell process!

P.S. I use Flyspell with the following (standard) configuration:

  (add-hook 'after-init-hook
            (lambda ()
              (add-hook 'text-mode-hook #'flyspell-mode)
              (add-hook 'prog-mode-hook #'flyspell-prog-mode)))

I am unable to reproduce using the latest Org.

TIL!  Thank you.

> I am unable to reproduce using the latest Org.

I apologize for not providing a sequence of reproduction steps.

Upon further investigation, Org frequently starts and kills the
spellchecker when the document contains `LocalWords' comments.

1. Start Emacs

   emacs -Q

2. Configure Flyspell

   (add-hook 'text-mode-hook #'flyspell-mode)
   (add-hook 'prog-mode-hook #'flyspell-prog-mode)

3. Create a new Org file

   # LocalWords: xyz
   
   Hello there!

4. Export the file to HTML

Expected:

  No Ispell process started on export.

Actual:

  A new Ispell process started on export.

P.S. I also see Org starting Ispell over and over when holding down
`C-v' in a long document that contains lots of scattered `LocalWords'
comments.

Confirmed.
This is because `org-html-final-function' uses `mhtml-mode' to indent the
resulting html file. `mhtml-mode' unconditionally runs `prog-mode-hook'
thus starting Ispell.

We may try `delay-mode-hooks' around `set-auto-mode', but it is not
honoured by `mhtml-mode'. I guess we can report this as Emacs bug.

This sounds like a normal Ispell behaviour.

Fixed, on main.
The fix will only work in Emacs 30+, because it requires Emacs bug fix
described in https://debbugs.gnu.org/cgi/bugreport.cgi?bug=70671

Thanks. It definitely helps, but it's still quite slow. What's made the
biggest difference is is advising the relevant functions to turn flyspell
off beforehand and then turn it back on.

```
(defun azr/org-footnote-disable-flyspell (orig-fun &rest args)
  (flyspell-mode -1)
  (apply orig-fun args)
  (flyspell-mode))

(advice-add 'org-footnote-new :around #'azr/org-footnote-disable-flyspell)
(advice-add 'org-footnote-delete :around
#'azr/org-footnote-disable-flyspell)
```

Best,
Alan

Sure, but it is not going to help others.

Could you try to produce the profile using Org 9.5.5 and Org 9.6?
I am wondering if there is anything in Org 9.6 that is slowed compared
to Org 9.5.5.

Happy to. What is the best way to temporarily downgrade to 9.5.5? I install
Emacs through this <https://aur.archlinux.org/packages/emacs-git> Arch AUR
package, which installs the latest version of Org automatically.

Best,

If you have Emacs 28, Org 9.5.5 is built-in there.
Or you can git clone Org repo, checkout release_9.5.5, and use it in
front of Emacs load-path when loading Emacs. See
https://orgmode.org/manual/Installation.html
