Prototype vs Module pattern performance (v180)

Revision 180 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 = [];
var o = new Klass1()
objs.push(Klass1());

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

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

while (i--) {
  o.bar;
  o.foo;
}
ready
