pollingDuplexHttpBinding - Super Slow / Delay

pollingDuplexHttpBinding - Super Slow / Delay

Hi ,

I'm trying few days to googling and fix it , but only fails , ( found few posts about the subject , but failed , or didn't undetstand )

My WCF Service connects to WPF application wsDualHttpBinding  without problem , very fast , any service publish event I get it on the second.

with Silverlight , pollingDuplexHttpBinding   , I get the service publish  event after 30+- seconds delay after the WPF app got it,

I though about going to TCP which is much faster as I read , but  I prefer fix this if possbile  (configuration is ready ^^ )

( can both Silverlight&WPF connecrt to the TCP binding ? )

Tried both deploy on IIS with debug=false , same,

Silverlight Client Code :

var address = new EndpointAddress("http://localhost/TheWCFSevice/Service1.svc/pollingDuplexHttpBinding");    var binding = new PollingDuplexHttpBinding(PollingDuplexHttpSecurityMode.None)  {  InactivityTimeout = TimeSpan.FromMinutes(60),  ReceiveTimeout = TimeSpan.FromMinutes(60),  MaxReceivedMessageSize = 2147483647,  MaxBufferSize = 2147483647,  OpenTimeout = TimeSpan.FromMinutes(5),  CloseTimeout = TimeSpan.FromMinutes(5),  DuplexMode = PollingDuplexMode.MultipleMessagesPerPoll,  SendTimeout = TimeSpan.FromMinutes(5),    };    ObjProxy = new WCFService.Service1Client(binding, address);

WCF Service - Web.config :
