[PERFORMANCE] Why some org code is so deep invoked?

[Christopher M. Miles]

When I profiling Org Agenda generation, I found that org code is deeply invoked 
in Emacs profiler report.

My Question:

- What reason caused this situation?
- Can Org Mode optimize those deeply invoked code?

I have option ~org-agenda-start-with-clockreport-mode~ enabled. And have lot 
files in ~org-agenda-files~ list:

#+begin_src emacs-lisp
(length org-agenda-files)
#+end_src

#+RESULTS[(2022-08-12 08:29:28) 1c2c57fd8db39360b33abd3465e5ebb26c817627]:
: 46

And here is those files lines size:

#+begin_src emacs-lisp :results value verbatim
(sort
 (let ((return '()))
   (dolist (file org-agenda-files
                 return)
     (when-let ((buffer (get-buffer (file-name-nondirectory file))))
       (with-current-buffer buffer
         (setf return
               (add-to-list 'return (count-lines (point-min) (point-max))))))))
 '>)
#+end_src
