I found all Squeak rendering (not just Morphic) to be slow. I suspect 
the bottle neck has more to do with the rendering architecture than too 
many messages sends.

The characters are rendered from a texture, so you could certainly 
render them onto a surface if you wanted to. Either way, you get 
excellent performance because you keep the data close to the logic and 
let the graphics hw do the heavy lifting.
