Disable Server 2008 TCP Chimney Offload

TCP Chimney Offload is a networking technology that helps transfer the workload from the CPU to a network adapter during network data transfer. In Windows Server 2008, TCP Chimney Offload enables the Windows networking subsystem to offload the processing of a TCP/IP connection to a network adapter that includes special support for TCP/IP offload processing.

TCP Chimney Offload is available in all versions of Windows Server 2008 and Windows Vista. Both TCP/IPv4 connections and TCP/IPv6 connections can be offloaded if the network adapter supports this feature.

Disable TCP Chimney Offload from command line:

netsh int tcp set global chimney=enabled

The above command disables TCP Chimney Offload for the operating system.
