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:

(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.
