Receive Side Scaling
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 for more
information.

for the team.

automatically be
disabled for the team.
- If a non-Intel adapter is added to a team, RSS will automatically be disabled for the
