各大主流.Net的IOC框架性能测试比较

 在上一篇中，我简单介绍了下Autofac的使用，有人希望能有个性能上的测试，考虑到有那么多的IOC框架，而主流的有：Castle Windsor、微软企业库中的Unity、Spring.NET、StructureMap、Ninject等等。本篇文章主要针对这些IOC框架编写测试程序。

Autofac下载地址：http://code.google.com/p/autofac/

Castle Windsor下载地址：http://sourceforge.net/projects/castleproject/files/Windsor/2.5/Castle.Windsor.2.5.3.zip/download

Unity下载地址：http://entlib.codeplex.com/

Spring.NET下载地址：http://www.springframework.net/

StructureMap下载地址：http://sourceforge.net/projects/structuremap/files/

Ninject下载地址：http://ninject.org/download

其中，测试程序均采用最新的类库。

基础工作

1、程序还是引用上一篇的示例作为测试背景。

2、编写一个性能计数器，这里我采用老赵写的一个CodeTimer的类，具体介绍见：http://www.cnblogs.com/JeffreyZhao/archive/2009/03/10/codetimer.html

使用方式类似于：

int iteration = 100 * 1000;string s = ""; CodeTimer.Time("String Concat", iteration, () => { s += "a"; }); StringBuilder sb = new StringBuilder(); CodeTimer.Time("StringBuilder", iteration, () => { sb.Append("a"); });

3、编写一个IRunner运行接口：

public interface IRunner {     void Start(RunType runType); }

以及RunnerBase抽象基础运行类：

public abstract class RunnerBase {     private int _iteration = Convert.ToInt32(System.Configuration.ConfigurationSettings.AppSettings["Iteration"] ?? "10000");     internal int Iteration     {         get { return _iteration; }     }
    internal void Time(Action action)      {          CodeTimer.Time(Name, Iteration, action);      }
    protected abstract string Name { get; }  } 

这里_iteration表示测试运行次数，通过配置文件来设置值。Time方法通过计数器对action方法进行Iteration次迭代。

编写一个RunManager的运行管理器：

public class RunManager  {      public static void Start(IRunner runner)      {          Start(runner, RunType.Transient);      }
    public static void Start(IRunner runner, RunType runType)      {          runner.Start(runType);      }  }

在测试中，我采用两种方式的性能比较，一个是单例状态，一个是非单例状态：

/// <summary>  /// 运行状态  /// </summary>  public enum RunType  {      /// <summary>      /// 单例      /// </summary>      Singleton,
    /// <summary>      /// 瞬时      /// </summary>      Transient  } 

好了，现在我的程序只要继承RunnerBase以及IRunnre接口，就可以实现各个IOC框架的初始化装配的工作了。基础工作已经做好。

各个IOC框架测试程序

1、Autofac：

public class AutofacRunner : RunnerBase, IRunner  {      protected override string Name      {          get { return "Autofac"; }      }
    public void Start(RunType runType)      {          var builder = new ContainerBuilder();
        //if (runType == RunType.Singleton)          //    builder.RegisterType<DatabaseManager>().SingleInstance();          //else          //    builder.RegisterType<DatabaseManager>();          //builder.RegisterType<SqlDatabase>().As<IDatabase>();          ////builder.RegisterModule(new ConfigurationSettingsReader("autofac"));          builder.RegisterType<SqlDatabase>().As<IDatabase>();          if (runType == RunType.Singleton)              builder.Register(c => new DatabaseManager(c.Resolve<IDatabase>())).SingleInstance();          else              builder.Register(c => new DatabaseManager(c.Resolve<IDatabase>()));  
        var container = builder.Build();
        Time(() =>          {              var manager = container.Resolve<DatabaseManager>();              manager.Search("SELECT * FROM USER");          });
        container.Dispose();      }  } 

2、Castle Windsor：

public class WindsorRunner : RunnerBase, IRunner  {      protected override string Name      {          get { return "Castle Windsor"; }      }
    public void Start(RunType runType)      {          var container = new WindsorContainer();          if(runType == RunType.Singleton)              container.Register(Component.For(typeof(DatabaseManager)).LifeStyle.Singleton);          else              container.Register(Component.For(typeof(DatabaseManager)).LifeStyle.Transient);
        container.Register(Component.For(typeof(IDatabase)).ImplementedBy(typeof(SqlDatabase)));
        Time(() =>          {              var manager = container.Resolve<DatabaseManager>();              manager.Search("SELECT * FROM USER");          });      }  } 

3、Unity：

public class UnityRunner : RunnerBase, IRunner  {      protected override string Name      {          get { return "Unity"; }      }
    public void Start(RunType runType)      {          var container = new UnityContainer();          if(runType == RunType.Singleton)              container.RegisterType<DatabaseManager>(new ContainerControlledLifetimeManager());          else              container.RegisterType<DatabaseManager>(new TransientLifetimeManager());          container.RegisterType<IDatabase, SqlDatabase>();
        Time(() =>              {                  var manager = container.Resolve<DatabaseManager>();                  manager.Search("SELECT * FROM USER");              });      }  } 

4、Spring.NET：

public class SpringRunner : RunnerBase, IRunner  {      protected override string Name      {          get { return "Spring.NET"; }      }
    public void Start(RunType runType)      {          string databaseManagerName;          if (runType == RunType.Singleton)              databaseManagerName = "DatabaseManager_Singleton";          else              databaseManagerName = "DatabaseManager_Transient";
        Time(() =>          {              IApplicationContext context = ContextRegistry.GetContext();              var manager = (DatabaseManager)context.GetObject(databaseManagerName);              manager.Search("SELECT * FROM USER");          });      }  } 

5、StructureMap：

public class StructureMapRunner : RunnerBase, IRunner  {      protected override string Name      {          get { return "StructureMap"; }      }
    public void Start(RunType runType)      {          ObjectFactory.Initialize(container =>          {              if (runType == RunType.Singleton)                  container.ForRequestedType<DatabaseManager>().Singleton();              else                  container.ForRequestedType<DatabaseManager>();              container.ForRequestedType<IDatabase>().TheDefaultIsConcreteType<SqlDatabase>();          });
        Time(() =>              {                  var manager = ObjectFactory.GetInstance<DatabaseManager>();                  manager.Search("SELECT * FROM USER");              });      }  } 

6、Ninject：

public class NinjectRunner : RunnerBase, IRunner  {      protected override string Name      {          get { return "Ninject"; }      }
    public void Start(RunType runType)      {          IKernel kernel = new StandardKernel(new MyNinjectModule(runType));
        Time(() =>          {              var manager = kernel.Get<DatabaseManager>();              manager.Search("SELECT * FROM USER");          });      }  } 

客户端测试程序

static void Main(string[] args)  {      CodeTimer.Initialize();
    Console.WriteLine("IOC - Singleton");      // Autofac Singleton      RunManager.Start(new AutofacRunner(), RunType.Singleton);             // Castle Windsor      RunManager.Start(new WindsorRunner(), RunType.Singleton);      // Unity      RunManager.Start(new UnityRunner(), RunType.Singleton);      // Spring.NET      RunManager.Start(new SpringRunner(), RunType.Singleton);      // StructureMap      RunManager.Start(new StructureMapRunner(), RunType.Singleton);      // Ninject      RunManager.Start(new NinjectRunner(), RunType.Singleton);
    Console.WriteLine("===================================");      Console.WriteLine("IOC - Transient");      // Autofac Singleton      RunManager.Start(new AutofacRunner(), RunType.Transient);      // Castle Windsor      RunManager.Start(new WindsorRunner(), RunType.Transient);      // Unity      RunManager.Start(new UnityRunner(), RunType.Transient);      // Spring.NET      RunManager.Start(new SpringRunner(), RunType.Transient);      // StructureMap      RunManager.Start(new StructureMapRunner(), RunType.Transient);      // Ninject      RunManager.Start(new NinjectRunner(), RunType.Transient);
    Console.ReadKey();  } 

通过修改App.config的Iteration配置值，来设置迭代次数。

<appSettings>   <add key="Iteration" value="100000" /> </appSettings>

运行结果

1、Iteration=1000：

分析：在千数量级时，Autofac，CastleWindsor、StructureMap基本差不多，效率上比其他的要高。

2、Iteration=10000：

分析：在万数量级时，Autofac，CastleWindsor，StructureMap基本效率还是差不多，其中StructureMap效率稍稍有些下降；Spring.NET以及Ninject的性能比较低。

3、Iteration=100000：

分析：在十万数量级时，CastleWindsor的效率开始下降，而在Transient方面，StructureMap和Autofac基本差不多。

4、Iteration=1000000：

分析：在百万数量级时，Autofac和StructureMap两者还是保持比较高的效率，并且在Transient方面，StructureMap已经超过了Autofac。

总结：从测试中，可以看出Autofac和StructureMap在性能上面还是体现出比较大的优势，Ninject可以说性能上较低。而Spring.NET不仅仅专注于IOC方面，它还专注于其他方方面面的功能，所以在IOC方面的性能不是太高。另外，微软的Unity中规中矩，性能较为稳定，也是一个不错的选择。另外，可能测试程序会有所偏差，希望大家也能够指出问题！
