WCF vs. .Net Remoting

Question

according to this article, WCF with named pipes is the best choice for IPC, and it is around 25 % faster than .Net Remoting.

I have the following code that compares WCF

Answer 1

Debuggers are not real measure when try to compare the performance , here is what I did and got WCF Kicking out Remoting from the ring ;)

1) Also modified your test to run it from same program/exe

  namespace ConsoleApplication6
{
  [ServiceContract]
  internal interface IRemote
  {
    [OperationContract]
    string Hello(string name);
  }

  [ServiceBehavior]
  internal class Remote : MarshalByRefObject, IRemote
  {
    public string Hello(string name)
    {
      return string.Format("Hello, {0}!", name);
    }
  }

  class Program
  {
    private const int Iterations = 5000;

    static void Main(string[] p)
    {
      TestWcf();
      TestRemoting();
    }


    static void TestWcf()
    {
      var address = "net.pipe://localhost/test";

      var host = new ServiceHost(typeof(Remote));
      host.AddServiceEndpoint(typeof(IRemote), new NetNamedPipeBinding(NetNamedPipeSecurityMode.None), address);
      host.Open();

      var proxy = ChannelFactory.CreateChannel(new NetNamedPipeBinding(NetNamedPipeSecurityMode.None), new EndpointAddress(address));

      TestWcf(proxy, Iterations);
      TestWcf(proxy, Iterations);
      TestWcf(proxy, Iterations);
      TestWcf(proxy, Iterations);
      TestWcf(proxy, Iterations);

      Console.WriteLine("WCF done");

      host.Close();
    }

    private static void TestWcf(IRemote proxy, int iterations)
    {
      var start = DateTime.Now;

      for (var i = 0; i < iterations; i++)
      {
        proxy.Hello("Sergey");
      }

      var stop = DateTime.Now;

      Console.WriteLine("Wcf: {0} ms.", (stop - start).TotalMilliseconds);
    }

    static void TestRemoting()
    {
      var domain = AppDomain.CreateDomain("TestDomain");

      var proxy =
          (IRemote)
          domain.CreateInstanceFromAndUnwrap(Assembly.GetEntryAssembly().Location, "ConsoleApplication6.Remote");

      TestRemoting(proxy, Iterations);
      TestRemoting(proxy, Iterations);
      TestRemoting(proxy, Iterations);
      TestRemoting(proxy, Iterations);
      TestRemoting(proxy, Iterations);
      Console.WriteLine("Remoting done");
      Console.ReadKey();
    }

    private static void TestRemoting(IRemote proxy, int iterations)
    {
      var start = DateTime.Now;

      for (var i = 0; i < iterations; i++)
      {
        proxy.Hello("Sergey");
      }

      var stop = DateTime.Now;

      Console.WriteLine("Remoting: {0} ms.", (stop - start).TotalMilliseconds);
    }
  }

}

2) Compile it in release mode and ran it outside debugger.

here is my output
