Agreed. I don't understand it either. If running two tasks on two cores takes twice as long, then I'm better off running two tasks one after another on a single core. But if it's CPU time is the interesting result that the increased clock on the E-core when task is assigned means that assigning task to E-core doubles throughput so that two tasks spend equal CPU time as one task? That's interesting but it wasn't clear to me.
