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

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