I kind of doubt the performance figures you give. 4 to 5 full screen alpha blended layers on the droid will give you around 30 to 35 fps. I assume you only measure the time it takes to execute your OpenGL commands. The real deal is measuring the delta time between the last and the current frame. Actual drawing is mostly performed on eglSwapBuffers which is executed after the Renderer.drawFrame() method is executed.
