Thanks for your latest diff! The overall current performance is quite satisfactory. I describe in two cases as Karthik's classification. 1. When running org-latex-preview-all inside an org file (about 700 fragments), Emacs is not unresponsive in comparison to the past, and the fragments rendering is much more faster than before (taking 2-3s approximately on my modern processor, an R7-5800H). 2. When running save-buffer-kill-emacs, the time has been reduced from about 5 minutes to 2-3s (turning off org-roam-autosync-mode). For my current needs, this speed is more than satisfactory. However, according to previous statement last year, this speed would rapidly decrease as the scale of the fragments increase because of the usage of pp, correct? I attach the profiler for the convenience of any future performance enhancement. P.S. During the test, I discovered that, if someone uses org-roam and turns on autosync-mode, the `rename-file` function would be overloaded by `org-roam-db--autosync-rename-file-a`, which would occupy half of the total time. Turning off the autosync-mode temporarily will solve this performance problem. In my view, org-persist only process those files in memory and the cache directory and not interactive with the org-roam-directory, right? P.S.2 I am pretty new to Emacs community and I cc this reply to emacs-orgmode@gnu.org. I hope it would appear in the org maillist archive.

It takes about 5 minutes since I have a large number of fragments. Except for removing the hook directly (I do not know what is the consequence of the brute-force approach actually), is there any choice to moderate this “bug”? You can try the last diff I shared in this thread. Or you can disable caching of latex previews (the Teco's branch should have such option). -- Ihor Radchenko // yantar92, Org mode maintainer, Learn more about Org mode at <https://orgmode.org/>.
