It doesn't look as if these profiles are complete (you can see it in the 
first picture where WorldState>>doOneCycleFor: only accounts for 21% of 
the total time spent). It would be good if you a) include all processes 
in the profile and b) copy the text into the email (instead of taking a 
picture) so that we can look at the the various parts in context.
