I ran your sample under a profiler and saw obvious problems with CPU and memory performance, and there are obvious problems with GPU efficiency based on your rendering model. This is not subjective; profiling is objective.
P.S. JSIL doesn't compete with your library, it's a cross-compiler. Are you angry because I gave a specific example of how I used one of the optimizations I suggested, or just because I'm pointing out that your website is dishonest?
EDIT: I shouldn't have to point this out either, but saying 'this text you wrote is dishonest' is not a personal attack. It's an objective criticism of your writing. Saying 'it's dishonest to call this library fast because x' is also not a personal attack, it is an objective criticism of your code.
If I called you a liar or a dishonest person, that would be a personal attack. I have not done that. I could certainly make that claim based on your argumentative style in this thread, but I shall not.
