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

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!
