Performance

• KineticJS vs Fabric - http://jsperf.com/fabricjs-vs-kineticjs/10 Fabric is slightly faster because of the new StaticCanvas class. When using regular Canvas, KineticJS is much faster. It might be cool to create a StaticStage or StaticLayer class for Kinetic
• KineticJS vs Easel.js (http://jsperf.com/kineticjs-vs-easeljs-render/12) - EaselJS is slightly faster. Like Fabric though, it only uses a single canvas. I bet once the StaticStage is implemented, Kinetic will be a bit faster when just pushing pixels. Still, Kinetic is the only library that supports layering. For real life applications, KineticJS will always be faster when the layers are utilized.
