Only 6 fps faster than drawrect for me on average.
Uploading data is big chunks is always going to be slow. The only way you can circumvent this is to devide your fake screen buffer up into smaller chunks. But even that goes out of the window when you edit the whole thing per frame as in this example. It'll still be the same amount of data going through the pipe.
In Blitz2Dish(so going to get sued for that name). you actually can write directly to memory bitmaps as well at blistering speeds. Like pixmaps but without the overhead of texture creation etc as it just blits directly onto the screen buffer.
