Idem for me. Slow(er) in Org buffer itself.

Fast(er) in dedicated buffer.

Maybe this is (partly?) due to the overlay I added:

#+begin_src emacs-lisp
                (overlay-put (make-overlay beg1 block-end)
                             'face 'org-block-background))
#+end_src

in function

#+begin_src emacs-lisp
(defun org-fontify-meta-lines-and-blocks (limit)
#+end_src

in file org.el.

Best regards,
  Seb
