Thanks for these details. I can report similar experiences with large files.

As far as I understand, large org-mode buffers are slow because there
are many overlays, which (unlike text properties), don't scale well:

(info "(elisp) Overlays")

This is right now an inescapable limitation of org-mode, since
outline-mode relies on overlays.

There was brief talk on emacs-dev of rewriting text-properties so that
outline-mode could use them instead of overlays, but I do not believe
the proposal was pursued further:
