各大主流.Net的IOC框架性能测试比较(转)

出处:/article/4758623.html

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！
