Continuing the exercice I found:

(elp-instrument-list '(org-agenda-next-line next-line line-move)) results in

org-agenda-next-line  12          0.016         0.0013333333
next-line             12          0.0           0.0
line-move             12          0.0           0.0


(elp-instrument-list '(org-agenda-next-line next-line line-move 
line-move-partial line-move-visual line-move-1)) results in

org-agenda-next-line  12          0.015         0.00125
next-line             12          0.0           0.0
line-move             12          0.0           0.0
line-move-partial     12          0.0           0.0
line-move-1           12          0.0           0.0


changing to agenda month view and "n"-ing through all entries results in:

org-agenda-next-line  93          0.2180000000  0.0023440860
next-line             93          0.016         0.0001720430
line-move             93          0.0           0.0
line-move-partial     93          0.0           0.0
line-move-1           93          0.0           0.0

further, after elp-instrument-package RET org RET (and doing lots of "n"s and 
"p"s)

scrolling with "n" and "p" runs smoothly now! Sigh! That means the slowness is 
connected to my .emacs and org settings!?
I'am afraid I have to go through all the settings and find the culprit.
