Or if the "optimisation" was key to getting acceptable performance,
maybe discourage the use of $...$ and emphasise the use of \(...\).  The
latter is less fragile and is easy to generate by typing $ using the
following function and binding:

#+begin_src emacs-lisp

  (defun yf/org-electric-dollar nil
  "When called once, insert \\(\\) and leave point in between.
  When called twice, replace the previously inserted \\(\\) by one $."
    (interactive)
    (if (and (looking-at "\\\\)") (looking-back "\\\\("))
        (progn (delete-char 2)
               (delete-char -2)
               (insert "$"))
      (insert "\\(\\)")
      (backward-char 2)))
  (define-key org-mode-map (kbd "$") 'yf/org-electric-dollar)
#+end_src

The problem with $ in org mode is that it is a valid standalone
character (i.e. currency symbol).  Having it perform two functions
(symbol and LaTeX directive) makes it difficult to optimise
performance.
