Receive Side Scaling

It gives the facility of distributing the load from the network adaptor to the CPU that works with multiple processors.

Network Direct Memory Access offers the facility of discharging memory copy operation which is the job of networking subsystem.

You can check out all these services on system by running the following command: netsh int tcp show global

TCP Global Parameters

From the image,we can see how the activation/deactivation mode of the services can be checked out. If we talk about SQL 2008 and above versions, the TCP Chimney. To check out if the TCP Chimney offload is in functional state or not, run the command: netstat –t.

Network Direct Memory Access

NetDMA offers the services for offloading the memory copy task that the networking subsystem executes to a dedicated direct memory access (DMA) engine. That too while receiving the network packets.
