Symptoms

Poor performance is observed for outbound web services.

With an ethernet sniffer, it is observed that although the data is returned promptly from the external system, it is not reaching Siebel until the TCP connection is closed.

HTTP 1.1 is used with KeepAlive, so the TCP connection is kept open for 15 seconds after the HTTP request has returned.  The requests are taking 15 seconds + to return.
