Hello All ,
Shell I use normal per vertex or normal per face ?
Is it look better if I use normal per vertex ?
Is performance are better when I use normal per face ?

You should use normals per vertex, shading looks lot better than with per face normals. As far as I know there is no significant difference in performance.
If you specify a normal per face, you need to split vertices because the same “vertex” will have different normals when used in different faces. Thus, performance will be worse than if you just use vertex normals.
Use per vertex normals for smooth objects (that is, objects where the angle of faces changes slowly). For sharp corners, use per face per vertex normals (that is, per vertex normals that have different values for the faces that are meeting).
