​RSS Queues and RSS Processors

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 processing is performed by a single processor, resulting in less efficient system cache utilization.
