Opening this file takes more than 10 seconds:

https://www.dropbox.com/s/tg7pr6tetlh7jwb/toc%2020200922%2007.00.01.org?dl=0

I also attach the profile.

I have org files which are much bigger, and they open almost instantly.

This is on Windows 10, emacs 26.3, all packages updated to the latest version.

Is there anything I can do to speed this up?

Thanks!

on emacs 27.1 on a Mac, this seems to take under a second to open for me.

Might be a good idea to profile the operation to see where it is 
spending time. Can you:

M-x profiler-start
C-x C-f (or whatever you are doing to open the file)
M-x profiler-report

Here's my output on your file:

Maybe that will help point you into the right (or at least a) 
direction.

I have no issue opening your file (under 1 second).

> I also attach the profile.

Looking at the profile, the problem seems to be with ivy. Can you try
opening the file without ivy. Something like

M-: (find-file "~/Org/notes.org") <RET>

P.S. You can also add notes to papers from org-ref. That is a great help
     when your paper database grow bigger.

Best,
Ihor

Attached the profile when i open with 'find-file'. It still seems to
call ivy-read, but the interesting thing is that now a lot of time is
apparently spent in 'url-http' functions. The file contains lots of
web links, so it seems emacs is trying to do something with them when
it really shouldn't...

Cheers,

Peter

Opens almost immediately for me.  Linux, recent emacs and org from git.

Ok, it turned out the url http functions also showed up when I was
trying to update packages. It seems I'm suffering from this bug:
https://emacs.stackexchange.com/questions/60560/error-retrieving-https-elpa-gnu-org-packages-archive-contents-error-http-400
and perhaps for some reason when opening the file through ivy, emacs
tried to update a package?

Anyway, I updated to emacs 27.1 to fix that particular bug, but the
file still loads very slowly. I'll report this to the ivy developers.
