Dynamic Floorfield is still calculated when all pedestrian have left
If you run a scenario with the dynamic floorfield, e.g. option QUEUEING instead of UNIT, the part of the simulation in which all pedestrians have already reached their target is significantly slower than the static floor field. The reason seems to be that the dynamic floor field is still calculated even though there are no pedestrians. This might slow down simulations especially for automatic parameter variation where the simulationTime cannot be set exactly to the expected finishTime.
