几个常用Json组件的性能测试
上一篇文章中我已经介绍了JsonBuilder方案的整体思路以及一个版本的雏形代码，他现在已经是可以使用的了，但是因为是实时反射的，所以效率并不高。
鉴于几位博友对Json转换组件的性能有兴趣，我先放几个常用组件的测试结果以供参考。下一篇在详细介绍JsonBuilder的优化工作
测试用例
using System;
using System.Collections.Generic; /// <summary> 用户对象
/// </summary>
public class User
{
public static User TestUser()
{//这里我尽量构造一个看上去很复杂的对象,并且这个对象几乎涵盖了所有常用的类型
User user = new User();
user.UID = Guid.NewGuid();
user.Birthday = new DateTime(, , , , , );
user.IsDeleted = false;
user.Name = "blqw";
user.Sex = UserSex.Male;
user.LoginHistory = new List<DateTime>();
user.LoginHistory.Add(DateTime.Today.Add(new TimeSpan(, , )));
user.LoginHistory.Add(DateTime.Today.Add(new TimeSpan(, , )));
user.LoginHistory.Add(DateTime.Today.Add(new TimeSpan(, , )));
user.LoginHistory.Add(DateTime.Today.Add(new TimeSpan(, , )));
user.LoginHistory.Add(DateTime.Today.Add(new TimeSpan(, , )));
user.Info = new UserInfo();
user.Info.Address = "广东省广州市";
user.Info.ZipCode = ;

user.Info.Phone.Add("手机", "");
user.Info.Phone.Add("电话", "");
user.Info.Phone.Add("短号", "");
user.Info.Phone.Add("QQ", "");
user.Double = Double.NegativeInfinity;

测试代码
测试方案1：微软自带的的 JavaScriptSerializer
引用组件：System.Web.Extensions（微软自带了，引用下就好）
string str = new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(User.TestUser());
//{"Self":null,"UID":"6f50b429-5c13-4875-a29a-e4bd8d7b2772","Name":"blqw","Birthday":"\/Date(530964000000)\/","Sex":0,"IsDeleted":false,"LoginHistory":["\/Date(1377129600000)\/","\/Date(1377137410000)\/","\/Date(1377146036000)\/","\/Date(1377163518000)\/","\/Date(1377184019000)\/"],"Info":{"Address":"广东省广州市","Phone":{"手机":"18688888888","电话":"82580000","短号":"10086","QQ":"21979018"},"ZipCode":510000},"Double":-Infinity}
测试方案2：Newtonsoft.Json
引用组件：Newtonsoft.Json.Net35.dll
string str = Newtonsoft.Json.JsonConvert.SerializeObject(User.TestUser());
//{"Self":null,"UID":"6f50b429-5c13-4875-a29a-e4bd8d7b2772","Name":"blqw","Birthday":"\/Date(530964000000+0800)\/","Sex":0,"IsDeleted":false,"LoginHistory":["\/Date(1377129600000+0800)\/","\/Date(1377137410000+0800)\/","\/Date(1377146036000+0800)\/","\/Date(1377163518000+0800)\/","\/Date(1377184019000+0800)\/"],"Info":{"Address":"广东省广州市","Phone":{"手机":"18688888888","电话":"82580000","短号":"10086","QQ":"21979018"},"ZipCode":510000},"Double":-Infinity}
测试方案3：Jayrock.Json
引用组件：Jayrock.Json.dll
JsonTextWriter jtw = new Jayrock.Json.JsonTextWriter();
Jayrock.Json.Conversion.JsonConvert.Export(User.TestUser(), jtw);
string str = jtw.ToString();
//{"uID":"6f50b429-5c13-4875-a29a-e4bd8d7b2772","name":"blqw","birthday":"1986-10-29T18:00:00.0000000+08:00","sex":"Male","isDeleted":false,"loginHistory":["2013-08-22T08:00:00.0000000+08:00","2013-08-22T10:10:10.0000000+08:00","2013-08-22T12:33:56.0000000+08:00","2013-08-22T17:25:18.0000000+08:00","2013-08-22T23:06:59.0000000+08:00"],"info":{"address":"广东省广州市","phone":{"手机":"18688888888","电话":"82580000","短号":"10086","QQ":"21979018"},"zipCode":510000},"double":-Infinity}
测试方案4：fastJSON.NET
引用组件：fastJSON.dll
JSONParameters p = new JSONParameters();
p.EnableAnonymousTypes
= p.IgnoreCaseOnDeserialize
= p.ShowReadOnlyProperties
= p.UseEscapedUnicode
= p.UseExtensions
= p.UseFastGuid
= p.UseOptimizedDatasetSchema
= p.UseUTCDateTime
= p.UsingGlobalTypes
= false;//所有参数为false,执行速度最快 string str = fastJSON.JSON.Instance.ToJSON(User.TestUser(), p);
//{"Self":null,"UID":"6f50b429-5c13-4875-a29a-e4bd8d7b2772","Name":"blqw","Birthday":"1986-10-29 18:00:00","Sex":"Male","IsDeleted":false,"LoginHistory":["2013-08-22 08:00:00","2013-08-22 10:10:10","2013-08-22 12:33:56","2013-08-22 17:25:18","2013-08-22 23:06:59"],"Info":{"Address":"广东省广州市","Phone":{"手机":"18688888888","电话":"82580000","短号":"10086","QQ":"21979018"},"ZipCode":510000},"Double":-Infinity}
测试方案5,6：QuickJsonBuilder,JsonBuilder
ps:以上几种类型都不支持循环引用,如果有,直接抛出异常
说明：QuickJsonBuilder就是我上篇中介绍的JsonBuilder的终极形态
QuickJsonBuilder jb = new QuickJsonBuilder();
jb.ToJson(User.TestUser());
//{"Self":null,"UID":"6f50b429-5c13-4875-a29a-e4bd8d7b2772","Name":"blqw","Birthday":"1986-10-29 18:00:00","Sex":"Male","IsDeleted":false,"LoginHistory":["2013-08-22 08:00:00","2013-08-22 10:10:10","2013-08-22 12:33:56","2013-08-22 17:25:18","2013-08-22 23:06:59"],"Info":{"Address":"广东省广州市","Phone":{"手机":"18688888888","电话":"82580000","短号":"10086","QQ":"21979018"},"ZipCode":510000},"Double":-Infinity}
ps:当Self指向自己本身的时候,将返回 "Self":undefined 用以区分空对象
测试方案7：ServiceStack.Text
引用组件：ServiceStack.Text.dll 抱歉我只找到4.0的
这个是后来补上的,测试代码中没有这个...
User.TestUser().ToJson();
//{"UID":"48d4624ad0c8475094d00fc769c7129f","Name":"blqw","Birthday":"\/Date(530964000000+0800)\/","Sex":"Male","IsDeleted":false,"LoginHistory":["\/Date(1377129600000+0800)\/","\/Date(1377137410000+0800)\/","\/Date(1377146036000+0800)\/","\/Date(1377163518000+0800)\/","\/Date(1377184019000+0800)\/"],"Info":{"Address":"广东省广州市","Phone":{"手机":"18688888888","电话":"82580000","短号":"10086","QQ":"21979018"},"ZipCode":510000},"Double":-Infinity}
ps:依然不支持循环引用,抛出堆栈异常

测试结果仅供参考
总结
可以看出基本所有组件在第一轮用时都是最长的,应该是在处理一些初始化和缓存的工作。
所以呢，我特别给出了1次的循环结果，
JavaScriptSerializer 可以看出在100次以内的时候微软的还是有一些优势的，随着次数增加性能就渐渐跟不上了
Newtonsoft.Json一直表现平平啊，没有特别突出就地方，就跟JsonBuilder比性能也没有好到那里去
Jayrock.Json 是昨天一位博友告诉我的，据说是淘宝sdk在用的，性能只能说，好差。。。
fastJSON.NET 确实是所有组件中最快的，QuickJsonBuilder也从中借鉴了一些处理方式
ServiceStack.Text 中规中矩吧比Newtonsoft.Json好一点点.就是我只找到4.0的拓展方法,不知道2.0下有没有相应的组件
好吧 我自己的组件我就不做评价了
