Take a close look at Exhibits A & B.
A: Left side has Bump Mapping
B: Right side has no Bump Mapping

Notice how subtle the light affects and plays over the reptile hide sofa bench cushion.

Granted, the custom texture I made is pretty elaborate and detailed in itself, but the Bump Map which is a greyscale duplicate of the texture adds that extra bit of surface mapping information for the lighting.

Side note: Renders at 640x480. High Quality settings
Bump Mapped version took 8:54 render time
No Bump Map version took 3:31 render time

The application had to calculate that much extra information for lighting in the scene.
