Revision 2 of this benchmark created on

Description

Testing the performance off a method with and without async.js

Setup

var callback = callback || function () {};
    
    cb = function(err) {
      var args = Array.prototype.slice.call(arguments, 1);
      if (args.length <= 1) {
        args = args[0];
      }
      callback.call(null, err, args);
    };
    
    fib = function(fn) {
      var numMax = 25
      for (i = 0, j = 1, k = 0; k < numMax; i = j, j = x, k++) {
        x = i + j;
        console.log(x);
      }
      fn(null, x);
    };
    
    COUNT = 50;
    
    list = [];
    for (var i = 0; i < COUNT; i++) {
      list.push(fib);
    }
