I am profiling my WCF services on New Relic. There is a WCF service which calls another WCF service. Now I suppose while calling another WCF service, when it creates request, somewhere the internal process writes headers to request stream which is slow some times. The traces I found in New Relic tells me that for a particular method of one of my WCF service which calls a method of my another WCF service, takes around 50-60 seconds, out of which 95-100 % of time is consumed by System.Net.ConnectStream.WriteHeaders.

Stream[url of WCF service/soap]: WriteHeaders -> 99.78 % time (approx 49 seconds).

I am not getting what it is and how to reduce this time ? I have searched and I didn't found what ConnectStream actually do or some details about it, so that I can find any way to lessen the amount of time its taking.

Please, let me know your suggestions.
