WCF Callback Object causing Tremendous latency

Jul 21 2008 5:03 PM
This is my first WCF project, so please bear with me.

My team developed a WCF Server/Client application that transfered data packs over an intranet using a TCP connection.  After finishing this version's development, we deployed the Client/Server app to the production environment.  On the production network, sending callback objects takes an incredibly long time and is very latent (500 milliseconds, compared to the 1 ms on our development network!). 

Does anyone have any ideas as to why this would happen?  We did traces between the cluient and the server on the production network and they came back within 1 ms.  I don't think its the code, as the code works fluidly and stably on the development network.  I think its a hardware, network, or windows issue but I really can't tell. 

Is there anyone with experience in this type of development that can suggest a fix?

Thank you in advance,
