<pre>V8 folks attempt to optimize ES6 performance based on the measurement with the benchmark called "six-speed".
While it is a collection of quite small microbenchmarks, it is still useful to ensure that our ES6 optimization covers major use cases.
For the macrobenchmarks, we already have one ;)
It is also tracked by arewefastyet.com <a href="http://arewefastyet.com/#machine=29&view=breakdown&suite=six-speed">http://arewefastyet.com/#machine=29&view=breakdown&suite=six-speed</a>.
