Prototype vs Module pattern performance (v20)

Revision 20 of this benchmark created on

Setup

Klass1 = function() {}
    Klass1.prototype.foo = function() {
      log('foo');
    }
    Klass1.prototype.bar = function() {
      log('bar');
    }
    
    Klass2 = function() {
      var foo = function() {
            log('foo');
          },
          bar = function() {
            log('bar');
          };
    
      return {foo: foo, bar: bar}
    }
    
    
    var FooFunction = function() {
      log('foo');
    };
    var BarFunction = function() {
      log('bar');
    };
    
    Klass3 = function() {
      return {foo: FooFunction, bar: BarFunction}
    }
    
    function Klass4() {
        this.foo = foo;
    
        function foo() {
            log('foo');
        }
        this.bar = bar;
    
        function bar() {
            log('bar');
        }
    }

Prototypal

  objs.push(new Klass1());
  o.bar;
  o.foo;
}

Module pattern
var i = 1000,
    objs = [];
while (i--) {
  var o = Klass2()
