You edit the first paragraph of a section, which is always fast. Try 1000 paragraphs in a single entry and move to the end of line anywhere in the last one. Also, try (require 'benchmark) (benchmark 1 '(org-element-at-point)) *twice* with or without `org-element-use-cache' in that last paragraph. Without cache, parsing doesn't scale. Some users reported already in th past having issues with speed on large documents. Regards,
