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? https://gist.github.com/karthink/0ac48411a81459c0f3fd7557c4e817db Karthik
