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

复制代码
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>/// </summary>
    Male,
    /// <summary>/// </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; }
}
测试用例
复制代码

  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)

复制代码
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}
复制代码

  测试方案2:Newtonsoft.Json

引用组件:Newtonsoft.Json.Net35.dll

复制代码
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}
复制代码

  测试方案3:Jayrock.Json

引用组件:Jayrock.Json.dll

复制代码
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}
复制代码

  测试方案4:fastJSON.NET

引用组件:fastJSON.dll

复制代码
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}
复制代码

  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

复制代码
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}
复制代码

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
