How does DRS in F1 provide such a boost?

Question

I see it as a small flap that opens up and it speeds up the cars by a large margin. How does something so small like a flap provide that much of a boost?

Answer 1

It reduces drag. At those speeds less drag is significant and can allow the car to go 6+ mph faster.

The higher the speed the more effective an aero gain is.
