My test shows that .NET Remoting is 1.5 times faster than WCF 4

Question

To indicate whether my project should migrate from a remote .net node to WCF, I extracted part of my network and implemented its WCF. I run the remote version and the wcf version and eventually find that remote work is 1.5 times faster than wcf , which is very different from the msdn article .

Testing Configuration

WCF and .NET Remoting are used as a tcp channel without encryption, not an app.config file. Compiled in release mode, without optimization.

Operations

What my program does is do it.

WCF test

Service host

ServiceHost host = new ServiceHost(typeof(Server), new Uri(string.Format("net.tcp://{0}:{1}/{2}", args[0], args[1], args[2]))); var binding = new NetTcpBinding(); binding.MaxReceivedMessageSize = 614400; binding.ReaderQuotas.MaxArrayLength = 512000;//a max picture of 500KB binding.Security.Mode = SecurityMode.None; host.AddServiceEndpoint(typeof(IServer), binding, string.Empty); host.Open(); 

Server

 [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single //, IncludeExceptionDetailInFaults = true , ConcurrencyMode = ConcurrencyMode.Reentrant )] public class Server : IServer { public EntryRequirement GetEntryRequirement() { return new EntryRequirement(new[] { "fuck", "sex" }, false); } public void AddClient() { var client = OperationContext.Current.GetCallbackChannel<IServerCallback>(); var p = client.Profile; var x = client.Password; System.Diagnostics.Debug.WriteLine(p); System.Diagnostics.Debug.WriteLine(x); } } 

Client side

  Player player = new Player(); player.Password = "12423"; player.Profile = new Contracts.PlayerProfile { Description = "I'm a man.", HeadImage = imageData, Name = "Loveright" }; var binding = new NetTcpBinding(); binding.Security.Mode = SecurityMode.None; Stopwatch watch = new Stopwatch(); watch.Start(); for (int i = 0; i < 20; i++) { ServerProxy server = new ServerProxy(player, binding, new EndpointAddress(string.Format("net.tcp://{0}:{1}/{2}", args[0], args[1], args[2]))); server.GetEntryRequirement(); server.AddClient(); } watch.Stop(); 

HeadImage is a 139KB image.

Player class

 [CallbackBehavior(ConcurrencyMode = ConcurrencyMode.Reentrant)] class Player : IServerCallback { public PlayerProfile Profile { get; set; } public string Password { get; set; } public void ClientCollectionChangedEventHandler(object sender, ControllersChangedEventArgs e) { } public void ClientUpdatedEventHandler(object sender, ClientUpdatedEventArgs e) { } } 

.NET Remoting Test

Host

  var serverProv = new BinaryServerFormatterSinkProvider(); serverProv.TypeFilterLevel = System.Runtime.Serialization.Formatters.TypeFilterLevel.Full; var clientProv = new BinaryClientFormatterSinkProvider(); IDictionary props = new Hashtable(); props["port"] = args[1]; props["name"] = "tcp server"; var channel = new TcpChannel(props, clientProv, serverProv); ChannelServices.RegisterChannel(channel, false); System.Runtime.Remoting.RemotingConfiguration.RegisterWellKnownServiceType(typeof(Server), args[2], System.Runtime.Remoting.WellKnownObjectMode.Singleton); 

Client

  var serverProv = new BinaryServerFormatterSinkProvider(); serverProv.TypeFilterLevel = System.Runtime.Serialization.Formatters.TypeFilterLevel.Full; var clientProv = new BinaryClientFormatterSinkProvider(); IDictionary props = new Hashtable(); props["name"] = "tcp client " + Guid.NewGuid(); props["port"] = 0; var channel = new TcpChannel(props, clientProv, serverProv); ChannelServices.RegisterChannel(channel, false); FileStream stream = new FileStream(@"logotz6.png", FileMode.Open); byte[] imageData = new byte[stream.Length]; stream.Read(imageData, 0, imageData.Length); stream.Close(); Player player = new Player(); player.Password = "12423"; player.Profile = new PlayerProfile { Description = "I'm a man.", HeadImage = imageData, Name = "Loveright" }; Stopwatch watch = new Stopwatch(); watch.Start(); for (int i = 0; i < 20; i++) { var serverProxy = (IServer)Activator.GetObject(typeof(IServer), string.Format("tcp://{0}:{1}/{2}", args[0], args[1], args[2])); serverProxy.GetEntryRequirement(); serverProxy.AddClient(player); } watch.Stop();

Result

So am I doing a test somewhere unfair to WCF?

Answer 1

Should it be code encoding a message?

Are you using binaryMessageEncoding instead of textMessageEncoding or soapMessageEncoding?

To do this, you can create a custom binding:

 internal sealed class MyBinding : CustomBinding { private static readonly BindingElementCollection elementCollection; static MyBinding() { MessageEncodingBindingElement encoding = new BinaryMessageEncodingBindingElement(); TcpTransportBindingElement transport = new TcpTransportBindingElement(); elementCollection = new BindingElementCollection(); elementCollection.Add(encoding); elementCollection.Add(transport); } internal MyBinding(string bindingName, string bindingNamespace) : base() { base.Namespace = bindingNamespace; base.Name = bindingName; } public override BindingElementCollection CreateBindingElements() { return elementCollection; } }
