[ZZ]Remoting技术：多线程中IpcChannel的性能太逊

原文出处：http://www.cnblogs.com/nevermad/archive/2009/11/16/1603752.html

网上都说Ipc通道的速度比Tcp、http通道快，也有相关的测试文章。但我在多线程测试中发现Ipc通道比Tcp慢了差不多20多倍，测试方法是在IIS6中创建Remoting通道，用WAS压力测试工具进行测试。IIS6中Web园设置为100个进程，核心请求队列设置为4000，然后打开WAS并设置1000个线程，每个线程2个连接。点击启动。

以下是WAS运行30s后的测试结果，WAS显示时间不准确是由于截图时间没有把握好

IPC通道

TCP通道：

对比可见，IPC通道在多线程状态下比TCP通道慢的太多了。

Tcp服务器端代码：

Code
        private void Form1_Load(object sender, EventArgs e)
        {
            BinaryServerFormatterSinkProvider sfsp = new BinaryServerFormatterSinkProvider();
            sfsp.TypeFilterLevel = TypeFilterLevel.Full;
            Hashtable props = new Hashtable();
            props["port"] = 8086;
            TcpChannel channel = new TcpChannel(props, null, sfsp);
            ChannelServices.RegisterChannel(channel, false);
            //SayHello sayHello = new SayHello();
            sayHello = new SayHello();
            RemotingServices.Marshal(sayHello, "SayHello");
            sayHello.ConnectedEvent += new DataDelegate.Connected(sayHello_ConnectedEvent);
            sayHello.DisConnectedEvent += new DataDelegate.DisConnected(sayHello_DisConnectedEvent);
        }

IPC服务器端代码

Code
       private void Form1_Load(object sender, EventArgs e)
        {
            BinaryServerFormatterSinkProvider sfsp = new BinaryServerFormatterSinkProvider();
            sfsp.TypeFilterLevel = TypeFilterLevel.Full;
            Hashtable props = new Hashtable();
            props["portName"] = "Chater";
            props["name"] = "ipc";
            props["authorizedGroup"] = "Everyone";

            IpcChannel channel = new IpcChannel(props, null, sfsp);
            ChannelServices.RegisterChannel(channel, false);

            sayHello = new SayHello();
            RemotingServices.Marshal(sayHello, "SayHello");
            sayHello.ConnectedEvent += new DataDelegate.Connected(sayHello_ConnectedEvent);
            sayHello.DisConnectedEvent += new DataDelegate.DisConnected(sayHello_DisConnectedEvent);
        }

远程代理类部分代码，

Code
        //这个数组是为了降低多线程竞争资源
        private Hashtable[] reDict = new Hashtable[MaxHashTables];


        public void AddEventReappear(string clientId, SayEventReappear re)
        {
            Random x = new Random();
            int i = x.Next(MaxHashTables);

            lock (reDict[i].SyncRoot)

            {
                this.reDict[i][clientId] = re;

            }
            
        }

TCP客户端代码，运行与IIS中

Code
        protected void Page_Load(object sender, EventArgs e)
        {

            string testL=new string (' ',36*8);
            SayHello sh;
            TcpChannel channel = null;
            string Identity=Request.QueryString["name"]??new Random().Next(10000000).ToString();
            if (ChannelServices.RegisteredChannels.Length == 0)
            {
                BinaryServerFormatterSinkProvider sfsp = new BinaryServerFormatterSinkProvider();
                sfsp.TypeFilterLevel = TypeFilterLevel.Full;
                Hashtable props = new Hashtable();
                props["port"] = 0;
                // props["exclusiveAddressUse"] = "false";
                //props["authorizedGroup"] = "Everyone";
                channel = new TcpChannel(props, null, sfsp);
                ChannelServices.RegisterChannel(channel, false);

            }
            sh = (SayHello)Activator.GetObject(typeof(SayHello), "tcp://localhost:8086/SayHello");
            SayEventReappear re = new SayEventReappear();
            re.OnSay += new SayHandler(re_OnSay);
            sh.AddEventReappear(Identity, re);
            Response.Write(testL);

                System.Threading.Thread.Sleep(120000);

            re.OnSay -= new SayHandler(re_OnSay);
            sh.SubEventReappear(Identity);

        }

IpcChannel的

       protected void Page_Load(object sender, EventArgs e)
        {

            string testL=new string (' ',36*8);
            SayHello sh;

            re.OnSay += new SayHandler(re_OnSay);
            sh.AddEventReappear(Identity, re);
            Response.Write(testL);

                System.Threading.Thread.Sleep(120000);

            re.OnSay -= new SayHandler(re_OnSay);
            sh.SubEventReappear(Identity);
