I turned jinx off as well.  The other culprit, for me, was wc-mode.  I
now count words explicitly when needed and use flyspell-buffer also
manually.

But I still see some lagging every now and again and keep
investigating...

Hi Bill

another sleepless night. Having something to distract me is helpful. In
this case, one of the root causes for my insufferable slowdown was not
org-mode but jinx (the spell checker). Without it, I do notice a slow down
when going through my slides, but much less.

Going back to ispell...

I wonder if those of us seeing this have something in common about our 
configurations.  Might it be a package that's getting in the way, and a change 
there is causing this?  Or does the profiling show it's in base Org?

Hi,

my profiling when deleting a line from a table:

 650  43% + redisplay_internal (C function)
 521  35% - command-execute
 470  31%  - byte-code
 470  31%   - read-extended-command
 470  31%- read-extended-command-1
 470  31% - completing-read-default
 443  29%  + redisplay_internal (C function)
  11   0%  - timer-event-handler
  11   0%   - apply
   7   0%+ jinx--timer-handler
   4   0%+ org-element--cache-sync
  51   3%  - funcall-interactively
  34   2%   + org-kill-line
  17   1%   + next-line
 200  13%   Automatic GC
  57   3% + ...
  57   3% + timer-event-handler

Interestingly enough, this redisplay_internal function seems to be the real
pain. I think we need to switch to the main
emacs devel list here...

Unlikely. Note the +. redisplay_internal can (and does) call Elisp code.
In particular fontification.

Any chance you can provide a reproducer starting from make repro?

Hi Ihor,

same here and changing to text-properties didn't help making editing org
files less bumpy and slow.
I don't know if 886 lines is really very much... but that's my org-beamer
size for a double lecture.

Hi Ihor,

No, `org-fold-core-style' is set to 'overlays.

This is strange. `org-fold-core--property-symbol-get-create' should be
very fast normally.

A blind guess: do you have `org-fold-core-style' set to 'text-properties?

Hello,

I also did noticed some slow-down in the most recent org. This is the CPU 
profiler report after typing some words in an org-file I'm working on:

6493  71% - redisplay_internal (C function)
6372  70%  - jit-lock-function
6323  69%   - jit-lock-fontify-now
6257  68%- jit-lock--run-functions
6257  68% - #
6246  68%  - font-lock-fontify-region
6191  68%   - font-lock-default-fontify-region
3300  36%- font-lock-fontify-keywords-region
2448  26% - org-activate-folds
2122  23%  - org-fold-core-get-folding-spec
2035  22% org-fold-core--property-symbol-get-create
 217   2%  + org-fold-previous-visibility-change
 178   1% - org-activate-links
 178   1%  - org-activate-links--overlays
   3   0%   - org-element-link-parser
   3   0%  org-link-expand-abbrev

Best,

Bruno.
