Forget everything, the geometry instancing is your best friend ! In the picture, I rendered 4800 2d rectangles in 1024x768 resolution. If each rectangle is rendered with one draw call, there are only 78 frames per second on my G1S. But if all of them are rendered by geometry instancing (which rendering 512 rectangles in one draw call), the fps jump to 662. (Of course, this is not exciting since you can do more complicated things with geometry instancing.)
