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(1986, 10, 29, 18, 00, 00); user.IsDeleted = false; user.Name = "blqw"; user.Sex = UserSex.Male; user.LoginHistory = new List<DateTime>(); user.LoginHistory.Add(DateTime.Today.Add(new TimeSpan(8, 00, 00))); user.LoginHistory.Add(DateTime.Today.Add(new TimeSpan(10, 10, 10))); user.LoginHistory.Add(DateTime.Today.Add(new TimeSpan(12, 33, 56))); user.LoginHistory.Add(DateTime.Today.Add(new TimeSpan(17, 25, 18))); user.LoginHistory.Add(DateTime.Today.Add(new TimeSpan(23, 06, 59))); user.Info = new UserInfo(); user.Info.Address = "广东省广州市"; user.Info.ZipCode = 510000; user.Info.Phone = new Dictionary<string, string>(); user.Info.Phone.Add("手机", "18688888888"); user.Info.Phone.Add("电话", "82580000"); user.Info.Phone.Add("短号", "10086"); user.Info.Phone.Add("QQ", "21979018"); user.Double = Double.NegativeInfinity; // user.Self = user; //这里是用来测试循环引用的解析情况 return user; } public User Self { get; set; } //User self /// <summary> 唯一ID /// </summary> public Guid UID { get; set; } /// <summary> 用户名称 /// </summary> public string Name { get; set; } /// <summary> 生日 /// </summary> public DateTime Birthday { get; set; } /// <summary> 性别 /// </summary> public UserSex Sex { get; set; } /// <summary> 是否删除标记 /// </summary> public bool IsDeleted { get; set; } /// <summary> 最近登录记录 /// </summary> public List<DateTime> LoginHistory { get; set; } /// <summary> 联系信息 /// </summary> public UserInfo Info { get; set; } public Double Double { get; set; } } /// <summary> 用户性别 /// </summary> public enum UserSex { /// <summary> 男 /// </summary> Male, /// <summary> 女 /// </summary> Female } /// <summary> 用户信息 /// </summary> public class UserInfo { /// <summary> 地址 /// </summary> public string Address { get; set; } /// <summary> 联系方式 /// </summary> public Dictionary<string, string> Phone { get; set; } /// <summary> 邮政编码 /// </summary> public int ZipCode { get; set; } }
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：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 是我确实是所有组件中最快的，QuickJsonBuilder也从中借鉴了一些处理方式
