CULL_FRONT and CULL_BACK should work exactly the same performance-wise.
With CULL_NONE, you are, in some way, doubling amount of polygons that
have to be processed (fill-rate wise). They are transported to GPU in
all cases, but CULL_* test is trivial and can discard triangle very,
very fast. With CULL_NONE, GPU have to draw it, compute most things and
then zbuffer comes into play.
