I think it's pretty fast, so I'd vote for keeping the good and simple
design of the org schedule import in contrast to reimplement the wheel
for a slight speedup.

Yeah, that would work.  However, org times are usually ranges like
10:00-12:00 which is 11 characters wide.  You don't want to prefix the
displayed items with that, because then you wouldn't see anything from
the item's description text.  So I'd prepend the times so that I can see
them when hoovering with the mouse on that item.  Of course, then
`string-less' won't sort according to date.

Right.  Maybe a good idea was allowing a custom sort function that sorts
the `contents' for one day in `cfw:org-schedule-period-to-calendar'.
There, you still have the 'time text property that you can use for
sorting.
