When I open a big Org file which contains many different languages source blocks. And when the Org file buffer is fontified when option `org-src-fontify-natively` is enabled. Org will try to load those major modes. Including major-mode-hook like "clojure-mode-hook", "emacs-lisp-mode-hook", "python-mode-hook" etc. But for fontify the source blocks, I don't think it is necessary to load those major-mode-hooks. Also they are slow. Like in my case, most of time is used for loading source blocks major-mode-hooks.
- clojure-mode-hook has CIDER etc - python-mode-hook has elpy etc - emacs-lisp-mode-hook has some utilities. Temporary disable those major-mode-hooks by set-local them to nil is a good solution to speed-up Org. WDYT? If I'm wrong, please give out some thought from you.
