Profiling results after byte compiling both org-notify.el and org-element.el
(the rest of org is uncompiled code):

So orgntf-todo-list takes the lion's share of the time but
most of it is the 15 calls to org-element-parse-buffer (I have
15 files in my org-agenda-files list).

BTW, I think the first line of the profile must be a remnant
from before, although I did do an elp-reset-all.
