+Test Case: Pmd RSS Performance
+===============================================
+
+The RSS feature is designed to improve networking performance by load balancing
+the packets received from a NIC port to multiple NIC RX queues.
+
+In order to get the best pmdrss performance, Server configuration are required:
+
+- BIOS
+
+ * Intel Hyper-Threading Technology is ENABLED
+ * Other: reference to 'Test Case: Single Core Performance Benchmarking'
+
+Run application using a core mask for the appropriate thread and core
+settings given in the following:
+
+  +----+----------+-----------+-----------------------+
+  |    | Rx Ports | Rx Queues | Sockets/Cores/Threads |
+  +====+==========+===========+=======================+
+  |  1 |     1    |     2     |      1S/1C/2T         |

+``note``: A queue can be handled by only one core, but one core can handle a couple of queues.
