Polygons are known to be of less performance and add some other oddities, because rendering of polygons can't be done with the usual algorithms. Therefore the graphics driver has to split polygons into triangles, which doesn't save you anything, as you could also do this in your code as well. Usually it is better to use GL_QUAD or GL_TRIANGLE (or better use the striped primitives).
