And there is also the matter of hardware evolution.

When I was running Pharo on my 2007 imac 20'' with dual core 2.GHZ , Morphic was slow. And by slow I mean that I could see it was struggling to move windows around. I could see windows flickering trying to render themselves moving around.

But now with my 2014 imac even though the screen is double the size and the resolution much bigger (27'' retina) , Morphic is now quite fast. The reason is of course the fact that the CPU is a quad core at 3 Ghz thats almost a 3x times increase in speed and it really shows.

Even when Pharo take full the huge area of 27'' Morphic is responsive and quite fast.�
