Looks acceptable to me. If you want performances, then you need a LCD controller which is RAM mapped through a DMA controller. It looks like it is not the case here, I don't think it is possible to do this with a Foxboard. So here, you have to use your CPU to the controller's own RAM through IO ports, which slows down the process. if you have 24 bits per pixel and a 320*240 resolution, that makes 3*320*240 = 614400 bytes to transfer to fill the screen, which takes a while through GPIO ports.
