RSS overcomes by allowing multiple processors to be involved. When a new inbound stream arrives on an adapter, a CPU is selected to process the operation using a mechanism that is very similar to the way that teaming selects a physical adapter for outbound communications. Any single incoming TCP stream will be processed by only one CPU; other streams may be distributed to other processors.

RSS is enabled globally by default and it is recommended that you leave it. To check the status of RSS, enter the following code at a PowerShell prompt:
