RSS can improve Web scalability and performance when there are fewer NICs than processors on the server. When all the Web traffic is going through the RSS-capable NICs, incoming Web requests from different connections can be simultaneously processed across different CPUs. It is important to note that due to logic in RSS and HTTP for load distribution, performance can be severely degraded if a non-RSS-capable NIC accepts Web traffic on a server that has one or more RSS-capable NICs. We recommend that you either use RSS-capable-NICs or disable RSS from the Advanced Properties tab. To determine whether a NIC is RSS-capable, view the RSS information in the Advanced Properties tab for the device.
