This applies only if your network adapter has an onboard processor: you can find out from the spec sheet whether or not it does. If it does, it has been designed to offload network processing computations from the CPU. This hack can reduce system slowdown during high-speed data transfers. Navigate to:
HLM\System\CurrentControlSet\Services\Tcpip\Parameters
Create a new DWORD value called DisableTaskOffload and set it to 0 to enable the NIC’s processor. Of course, if the key exists and is set to 1, reset it to 0. A restart is required for the change to take effect.
