When Receive Side Scaling (RSS) is enabled, all of the receive data processing for a particular TCP connection is shared across multiple processors or processor cores. Without RSS all of the processing is performed by a single processor, resulting in inefficient system cache utilization.
Notes
- This setting has no effect if your system has only one processing unit.
- RSS must be enabled for Intel® I/O Acceleration Technology to function.
- To enable RSS on Microsoft* Windows Server* 2003, you must install Microsoft's Scalable Networking Pack. The Scalable Networking Pack is part of Windows Server 2003 SP2. It is not included in SP1 and requires a separate download. See http://www.microsoft.com

RSS Configuration
RSS is enabled on the Advanced tab of the adapter property sheet. If your adapter does not support RSS, or if your operating system does not support it, the RSS setting will not be displayed.
Teaming
- If RSS is not enabled for all adapters in a team, RSS will automatically be disabled for the team.
- If an adapter that does not support RSS is added to a team, RSS will automatically be disabled for the team.
- If a non-Intel adapter is added to a team, RSS will automatically be disabled for the team.
- Non-Intel adapters with RSS enabled cannot be added to a team
