Here you mean time to tangle, correct?  (As opposed to exporting to
HTML/LaTeX/etc.)

I can confirm very long times to tangle a document with a structure like
yours.  I ran the emacs profiler
<https://www.gnu.org/software/emacs/manual/html_node/elisp/Profiling.html>
while tangling the document for 30 secs, then interrupted with C-g and
generated a report.  That is attached.
