Why are there 79 calls to org-agenda-next-line? AFAIK, there should be
just one for each "n" pressed. Maybe do M-x elp-reset-all, then press
"n", and M-x elp-results?

The thing is that org-agenda-next-line is very simple:

,----
| (defun org-agenda-next-line ()
|   "Move cursor to the next line, and show if follow mode is active."
|   (interactive)
|   (call-interactively 'next-line)
|   (org-agenda-do-context-action))
`----

and the calls to org-agend-do-context-action don't amount to much, so
essentially all of the time must be spent in the (call-interactively
'next-line).

Maybe M-x elp-instrument-function <RET> next-line <RET> will give some
more clues.  I assume call-interactively cannot be instrumented by elp
since it's in C.
