Well, in answer to question 1, you don't need a throttle to avoid system instability. You really use the throttle to keep your computer from becoming entirely unresponsive when you have multiple threads with high priority running simultaneously as fast as they can.

I don't know the answer to question 2 -- I suspect to find the answer you're going to have to do some deep hunting in the scheduler.

Just to clarify ... is your graph:

connect (source, A, sink)
connect (source, sink)

I don't know for certain why the loads are different, but I can make some educated guesses.  But, I'm also happy to defer to others who might know better. - MLD
