Is drawing with ofFbo more efficient than just drawing a single object?

Hi, I wonder how efficient it is to draw with ofFbo compared to common drawing.

I think it should be efficient if I grab many objects (i.e shapes, labels, images) all together and then draw just once.

But is there any benefit in efficiency, even compared to just drawing one single object?

For example, what if I grab and draw a circle(ofDrawCircle) with ofFbo in same size instead? what about label?(ofTruetypeFont) or an image?

I would like to know if there's any extra benefit to draw an object through ofFbo than just drawing in a common way.
