Problem appears after first jump using C-u C-c C-j `org-goto'. Actually a jump is not required, it is enough to get jump (refile) targets.
I hope, the following numbers are convincing enough. Second attempt to get list of properties is much slower than the first one.
#+begin_src elisp (require 'org-refile) (let ((org-refile-targets '((nil :maxlevel . 6))) (org-refile-use-outline-path 'file) (org-refile-use-cache t) (iters 10)) (cons (list (org-version)) (mapcar (lambda (f) (append (list f) (benchmark-run iters (funcall f)))) (list #'org-buffer-property-keys #'org-refile-get-targets #'org-buffer-property-keys)))) #+end_src git master: #+RESULTS: | 9.4.6 | | | | | org-buffer-property-keys | 0.065695 | 0 | 0.0 | | org-refile-get-targets | 1.836473 | 12 | 0.39498671199999985 | | org-buffer-property-keys | 0.563227 | 0 | 0.0 | elpa-org system package for Ubuntu-20.04 is even more slower: #+RESULTS: | 9.3.1 | | | | | org-buffer-property-keys | 0.242574778 | 0 | 0.0 | | org-refile-get-targets | 2.669112479 | 13 | 0.285175928 | | org-buffer-property-keys | 1.231223427 | 0 | 0.0 |The effect is noticeable for the doc/org-manual.org file from org sources though absolute numbers are well below delay that makes interaction incomfortable.
In the configuration above effect of `org-refile-use-cache' is crucial, contribution of `org-refile-use-outline-path' is noticeable but not so important.
My expectation is that neither `org-refile-use-cache' nor `org-goto' command should make adding property slower.
