The time saved is in proportion to the number of faces discarded out of the
total number of faces.
Every object in a scene is processed by the renderer, even objects that are off
camera and are not going to be present in the rendered view. A model that is
built with the intent of rendering will benefit from good layer management.
By turning off layers containing objects that are not in the view, you can
increase rendering speed substantially.

Minimize Intersecting and Coplanar Faces
Certain kinds of geometry create special rendering problems.
The complexity of an object relates to the number of its vertices and faces.
The more faces a model has, the longer it takes to render. Keep the geometry
of your drawing simple to keep rendering time to a minimum. Use the fewest
faces possible to describe a surface.
Intersecting Faces
Intersecting faces in a model occur when two objects pass through one other.
For conceptual design situations, simply placing one object through another
is a fast way to visualize how something will look. However, the edge created
where the two objects intersect can exhibit a rippled appearance.
In the following example, the edge appears rippled in the left image and much
cleaner after a Boolean union.
