As Greg said, comparing 703 with latest joyride may be the most
interesting thing to do.

What about the following:
- add logging.debug('TIME launch starts') at
activitieslist.ActivityEntry.__icon_button_release_event_cb
- add logging.debug('TIME launch finished') at activity.Activity.__canvas_map_cb
If we really want to take in account the redraw time (not sure myself
if it's worth), you could override Activity.do_expose_event() and move
the "launch finished" print after the call to the parent finishes.
Something like grep -h TIME logs/* | sort -n should give you a way to
see how much time took every launch.
Sounds good?
