My experience is exactly opposite. Or maybe I miss something. Can you
elaborate?

Did you do any benchmarks? I just tried

Outline path without cache:

(benchmark-run 1
  (goto-char (point-min))
  (while (re-search-forward "^\\*+" nil t)
    (org-get-outline-path t nil))) => (6.051079914 1 0.2864724879999869)

Outline path with cache:

(benchmark-run 1
  (goto-char (point-min))
  (while (re-search-forward "^\\*+" nil t)
    (org-get-outline-path t nil))) => (1.658461165 0 0.0)

Just cleanup heading text:

(benchmark-run 1
  (goto-char (point-min))
  (while (re-search-forward "^\\*+" nil t)
    (let ((case-fold-search nil))
      (looking-at org-complex-heading-regexp)
      (if (not (match-end 4)) ""
	;; Remove statistics cookies.
	(org-trim
	 (org-link-display-format
	  (replace-regexp-in-string
	   "\\[[0-9]+%\\]\\|\\[[0-9]+/[0-9]+\\]" ""
	   (match-string-no-properties 4)))))))) => (0.013364877 0 0.0)

Best,
Ihor
