v8 performance show

[timoxley]

I'd love to be able get @mraleph on a show to pick his brain about JavaScript performance concerns, such as optimisation killers & myths.

Would like to cover performance concerns of new ES features.
e.g. maybe they're slower now but do any new features offer better potential optimisation options for the future?

Similarly, I'd like to get @trevnorris (or someone else from io.js core with a performance focus) to talk about io.js performance.

Could bring in @thorsten to talk about his work getting more visibility into v8.
