Dan, what exactly in this discussion made you think that we don't care
about performance?
I am with Alex that there is enough time for moaning and complaining about
alleged performance problems when we have a real-world application
cross-compiled.
At the same time, I am convinced that if there is a performance bottleneck,
it will be in the rendering (canvas, DOM), not in the actual application
code. For example, our complex browser UI application only spends about 10%
CPU time in JavaScript code. All the rest is the browser computing styles,
DOM repaint / reflow, and the actual rendering.
My experiments with running cross-compiled Flash games on iOS had their
best performance boost with every iOS update, providing increased canvas
rendering speed and JavaScript performance.
