I'd be interested to hear TJ's answer on this eToke...
Because I was asking from very similar questions of support & TJ recently... namely that equivalent AFL on charts seems to execute much quicker than a scan or exploration. Which obviously leads one to think that other operations that occur in a scan or exploration, outside of the AFL execution, are what take the time...
Why this time is greater with a streaming feed I don't know...
