Topic: [IIS, network] a call Time delay

I welcome . The task from the client got to me here on  I will as much as possible simplify. There is https a page, on it on actions of the person requests to us in system (POST) become. Server Win2012r2, WCF application under IIS'. Sometimes clients have a long call to us, and it looks as the big time delay in response, to tens seconds. In most WCF application the call is processed for units of milliseconds. Ping to the server small 100-200, clients in states, a server (the selected, 8 kernels, 96  the RAM, is pure under us) in germanium in a data-center. Where time not clearly leaves. With what to begin? The methods , are fulfilled quickly, time delays are not present. I sin on IIS, on it some applications are twisted, but all exposes restrictions on usage CPU, or a network. Here so looks har a broad gull from the client.

On a site  found: the Tab "Tajmingi" breaks network request about the following stages defined in the specification of HTTP-archive (HAR): the Name the Description Lock (Blocked) Time spent in queue of waiting for creation of network connection. The browser superimposes restriction on number of simultaneous connections with one server. In by default it is 6, but it can be changed, using property network.http.max-persistent-connections-per-server. If all connections are used, the browser cannot download more , until then while one of connections will not be released. Probably a problem not server, but client.

What at WCF-service InstanceContextMode and ConcurrencyMode? Probably, the combination at which service during each moment of time processes only one request is used, and remaining requests wait in queue.... <<RSDN@Home 1.0.0 alpha 5 rev. 0>>

Single, ConcurrencyMode = ConcurrencyMode. Multiple WCF uses stream date transmission? If uses that it is necessary to include asynchronous stream transmission still.
