the result of health-check is as follows.
I don't know why "Caching with org-persist" is ON. The value of
`org-latex-preview-cache` is exactly "temp" now.

takes minutes to run
I am not kidding you in fact.
In each test, I execute
#+begin_src elisp
(org-latex-preview-clear-cache)
(setq org-latex-preview-cache 'temp)
#+end_src
and compile \(\alpha\), after the precompilation hint vanishes, I
execute (my-org-latex-preview-benchmark), and the result is always
around 5.5s. I think this time is mistaken, since by my naked eyes,
the fragments around \(\alpha\) only take 0.5s-1s to be compiled and
shown.
5.5 seconds to compile 700 fragments without org-persist caching is a
really long time. I'm not sure what could be causing it. Can you
evaluate the code at this gist, then run M-x
org-latex-preview-check-health and supply the full output of this
command here?
