Asm.js: a strict subset of js for compilers

Re:Asm.js: a strict subset of js for compilers – working draft by evanprodromou on Friday February 15, 2013 @04:22PM (#5228760)

@dherman The document says, "extraordinarily optimizable". Do you have any numbers on that?

I'd love to see benchmarks from running asm.js-compatible JavaScript on e.g. SpiderMonkey versus an asm.js-optimizing SpiderMonkey.

Are we talking about incremental differences of 5%, 25%, even 50%, or orders-of-magnitude improvement?
