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。
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！
