This setting specifies the maximum number of outstanding packets permitted on the system. When the number of outstanding packets reaches this limit, the Packet Scheduler postpones all submissions to network adapters until the number falls below this limit.

Open your registry and find the key below.

Create a new DWORD value, or modify the existing value called 'MaxOutstandingSends' using the settings below.

Exit your registry, you may need to restart or log out of Windows for the change to take effect.
