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.
