And if you do it the right way, you don't need
a buffer of 100 000 lines or 10 000 iterations:
;; (insert (format "\n;; %f" (measure-time (point-at-final-line-1))))
;; 0.000154
;; (insert (format "\n;; %f" (measure-time (point-at-final-line-2))))
;; 0.000045
;; (insert (format "\n;; %f" (measure-time (point-at-final-line-3))))
;; 0.000014
