What is TCP Chimney Offload?

TCP Chimney Offload is a networking technology that allows the work associated with moving data across a network to be offloaded from the host computer's CPU to the network adapter. This helps improve the processing of network data on your computer or server without the need for additional programs or any loss to manageability or security. Programs that are currently bound by network processing overhead will generally scale better when used with TCP Chimney Offload.
