It's qualitatively different from Rainer's original profile.
org-agenda-next-line calls next-line and then
org-agenda-do-context-action.  In Rainer's profile, the latter took
almost no time, whereas in your faster system and also in mine, there is
a roughly 50/50 (or 40/60) split. In Rainer's later profiles, it's a
100/0 split.  That, along with the fact that the whole thing takes much
longer (somewhere from 10x to 50x[fn:1]) leads to the conclusion that
probably something is busted in next-line. So it doesn't mean much: just
gathering sticks for now and maybe we can build a house with them (then
again, maybe not).

I'd be very interested to learn what you find out.

Thanks,

Footnotes:
[fn:1] this kind of variance bothers me, but I guess I'll have to live with it.
