Sorry for the late response - missed this for a while.

That's still much more slow than not doing it - slightly modifying your
example,:

(progn
  (setq start (current-time))
  (let ((row 0) (log (time-add (current-time) '(0 1 0 0))))
    (while (< row 6543210)
      (setq row (1+ row))
      (when (time-less-p log (current-time))
        (setq log (time-add (current-time) '(0 1 0 0)))
        (message "row %d" row))))
  (setq end (current-time))
  (print (time-subtract end start)))

prints (0 43 386499 0) on my computer.

Removing the when clause:

(progn
  (setq start (current-time))
  (let ((row 0) (log (time-add (current-time) '(0 1 0 0))))
    (while (< row 6543210)
      (setq row (1+ row))))
  (setq end (current-time))
  (print (time-subtract end start)))

Results in:
(0 1 277641 0)

So adding the logging here slows it down by about 43x - It doesn't seem
worth it.
