Facilitated diffusion of glucose

I need a basic explanation of the difference in the rates at which glucose is transported across a cell membrane versus the concentration gradient of glucose. I am trying to understand the difference in diffusion through a lipid bilayer compared to facilitated diffusion. I could also really use help with finding online references on similar topics.

Glucose transport

Which is faster facilitated diffusion or active transport? I am trying to understand the which and why so I can make a graph.
