I followed these steps, found in one of my emails from two years ago,
using Emacs 28 downloaded from my distro and launched with '-Q', and a
bigger org file of about 250K, cause that's what I had handy:
Navigate to org-export--prune-tree in ox.el.
C-M-x to instrument it with Edebug.
Open a 150K org-mode file.
C-c C-e h H
Press Space repeatedly to step with Edebug
Result: stepping over any evaluation of the variable `data` takes a few
seconds.
Two years ago I called Edebug "very sluggish" in these circumstances but
I would not call it that today, so I think you can go ahead and close
this.
