Setting to speed up drop landing from plane to ground

Hello,
What setting do I change to speed up the time it takes from leaving the plane to landing on the ground? I am being told they want to get the drop faster and not stand around and wait for it to reach the ground, but I can't figure out what setting it would be. 

I think you can change this to achieve the result.
