Anyone can tell me why this is taking a tad over 11 seconds?

   1: class Program

   2: {

   3:     static void Main(string[] args)

   4:     {

   5:         try

   6:         {

   7:             var sw = Stopwatch.StartNew();

   8:             var host = new ServiceHost(new Srv(), new Uri("net.tcp://localhost:5123"));

   9:             host.AddServiceEndpoint(typeof (ISrv), new NetTcpBinding(), new Uri("net.tcp://localhost:5123"));

  10:             host.Open();

  11:  

  12:             var srv = ChannelFactory<ISrv>.CreateChannel(new NetTcpBinding(),

  13:                                                              new EndpointAddress(new Uri("net.tcp://localhost:5123")));

  14:             srv.Test("hello"); // if I remove this, it finishes in 0.3s - 0.5s

  15:  

  16:             host.Close();

  17:  

  18:             Console.WriteLine(sw.Elapsed);

  19:         }

  20:         catch (Exception e)

  21:         {

  22:             Console.WriteLine(e);

  23:         }

  24:     }

  25: }

  26:  

  27: [ServiceContract]

  28: public interface ISrv

  29: {

  30:     [OperationContract]

  31:     int Test(string x);

  32: }

  33:  

  34: [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Multiple)]

  35: public class Srv : ISrv

  36: {

  37:     public int Test(string x)

  38:     {

  39:         return x.GetHashCode();

  40:     }

  41: }

The reason that I care is that I am doing that in my tests, and this is significantly slow them down.

Is there anything that I am missing?
