Nodejs异步与同步方法负载测试

我一直在尝试为MVC框架创建一个视图模块。

我有2个版本的代码。一个同步和一个异步。
我知道我应该使用Async版本。但是,每当我通过AB进行负载测试时,我都会从Sync版本中获得更好的结果。

我做错了吗?这是我正在测试的代码示例

同步版本:

var fs = require('fs'),
    path = require('path'),
    dot = require('dot');
    Step = require('../libraries/step.js');

var view = function(){};

view.prototype = {

    renderView : function(source, data, layout, callback)
    {
        var self = this;

        if (typeof callback !== 'function') throw ViewCallbackException;

        layout = layout ? layout : 'default';

        (function(sources, datas, layouts, callbacks)
        {
            content = fs.readFileSync('./views/layouts/' + layouts + '/index.html', 'utf-8');
            callbacks(null, content);
        })(source, data, layout, callback);
    }
}

异步版本:

var fs = require('fs'),
    path = require('path'),
    dot = require('dot');
    Step = require('../libraries/step.js');

var view = function(){};

view.prototype = {

    renderView : function(source, data, layout, callback)
    {
        var self = this;

        if (typeof callback !== 'function') throw ViewCallbackException;

        layout = layout ? layout : 'default';

        (function(sources, datas, layouts, callbacks)
        {
            Step(
                function()
                {
                    fs.readFile('./views/layouts/' + layouts + '/index.html', 'utf-8', this);
                },
                callbacks
            );
        })(source, data, layout, callback);
    }
}
