Prototype vs Module pattern performance (v195)

Revision 195 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}}

Prototypal
var i = 1000,
    objs = [];
while (i--) {
  var o = new Klass1()
  objs.push(new Klass1());
  o.bar;
  o.foo;
}

Module pattern
var i = 1000,
    objs = [];
while (i--) {
  var o = Klass2()
  objs.push(Klass2());
  o.bar;
  o.foo;
}

Module pattern with cached functions
var i = 1000,
    objs = [];
while (i--) {
  var o = Klass3()
  objs.push(Klass3());
  o.bar;
  o.foo;
}
