One is that the Morphic-based UI is slow. You can see it by using the old MVC instead of Morphic which goes faster. Recently Morphic got slower on Pharo and it is now slower than in Squeak. It may be due to refactoring on Morphic in order to get it better, it may not be. I guess this is temporary. The second thing is that BitBlt is slow for 2 reasons: it is bit based and not vector based and its implementation half in the VM half in the image forces to copy a huge number of bits that could be avoided So the answer is that you need to contribute to the refactoring of Morphic or to Athens. GUI hardware acceleration is clearly not the problem yet.
