Disclaimer: The recommendations in Table 6 are intended to serve as guidance only for choosing the most suitable technology for specific server roles under a deterministic traffic pattern. User experience can be different, depending on workload characteristics and the hardware that is used.
If your hardware supports TOE, then you must enable that option in the operating system to benefit from the hardware’s capability. You can enable TOE by running the following command:
netsh int tcp set global chimney = enabled
Tuning the Network Adapter
You can optimize network throughput and resource usage by tuning the network adapter, if any tuning options are exposed by the adapter. Remember that the correct tuning settings depend on the network adapter, the workload, the host computer resources, and your performance goals.
