Remarks
The OutboundBufferSizeInBytes property sets the value of the SO_SNDBUF socket option on the TCP socket used by the StreamSocket. The default value is the local computer's default send buffer size. This value varies based on the system memory size. For more detailed information, see SOL_SOCKET Socket Options in the Windows Sockets documentation.
For most apps, this property should not be set since this disables TCP send auto-tuning by the system on this StreamSocket object. With TCP send auto-tuning disabled, network throughput is often worse especially on a connections with high latency. So this property should only be used in very specific situations.
The OutboundBufferSizeInBytes property must be set before the StreamSocket is connected. Setting this property after the StreamSocket is connected has no effect.
