If you ever inspect ember objects, they're huge, the properties/functions they have...

http://emberjs.com/api/classes/Ember.EachProxy.html

See the EachProxy class? Click on the class it extends.

http://emberjs.com/api/classes/Ember.Object.html

Oh look that object extends another class... apparently it uses Mixin to extend these classes maybe the apply function? If it's using prototype inheritance than looking up the prototype chain would be a performance hit IIRC.

I was doing Ember while during beta though. But during that time they were marketing Ember as smaller library and more performance than Angular.

The last bench mark I've seen, Ember library is much bigger and the performance was not that great compare to Angular...
