Org manual is ~5 times smaller than my file with notes and the former contains not so much not ASCII characters. For your test I get reasonable numbers Emacs-26 0.038 or 0.084 Emacs-27 0.0066 or 0.0092 I am comfortable with performance. It seems, some optimization has been done in Emacs since 26 release. I do not see dependence on Org version. While I work with my notes file, performance degrades after some operations. E.g. searches become significantly slower after caching refile targets. Previous discussion of the issue: Ihor Radchenko. Re: profiling latency in large org-mode buffers (under both main & org-fold feature) Sun, 27 Feb 2022 14:43:29 +0800. https://list.orgmode.org/87y21wkdwu.fsf@localhost My experience is that e.g. emacsclient with particular line causes several seconds hang. Despite improvements since Emacs-26 in line counting, still I believe that the `line-number-at-pos' function may still be excessively expensive in real live when unconditionally used just for a bit nicer logging.
