Prototype vs Module pattern performance (v36)

Revision 36 of this benchmark created by lenzhang 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 function() {
        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;
}
ready
Module pattern
var i = 1000,
    objs = [];
while (i--) {
  var o = Klass2()
  objs.push(Klass2());
  o.bar;
  o.foo;
}
ready
Module pattern with cached functions
var i = 1000,
    objs = [];
while (i--) {
  var o = Klass3()
  objs.push(Klass3());
  o.bar;
  o.foo;
}
ready
