That’s because we are converting the rendering into a bitmap that is after drawn for the vm… a complete inefficient mechanism. I have a running experiment for drawing directly in the canvas (using SDL2 library) and the tiger demo drops from eating 70% of cpu to 9% in my machine. Our idea is to move pharo in that direction for Pharo5 so next year we will be a lot better :) Esteban > > On Fri, Mar 6, 2015 at 6:28 PM, Alexandre Bergel <[email protected] > <mailto:[email protected]>> wrote: > This is really good that you are diving into Athens.
