+RTE Flow performance tool
+=========================
+
+Application for rte_flow performance testing.
+
+
+Compiling the Application
+=========================
+The ``test-flow-perf`` application is compiled as part of the main compilation
+of the DPDK libraries and tools.
+
+Refer to the DPDK Getting Started Guides for details.
+The basic compilation steps are:
+
+#. Set the required environmental variables and go to the source directory:
+
+	.. code-block:: console
+
+		export RTE_SDK=/path/to/rte_sdk
+		cd $RTE_SDK
+
+#. Set the compilation target. For example:
+
+	.. code-block:: console
+
+		export RTE_TARGET=x86_64-native-linux-gcc
+
+#. Build the application:
+
+	.. code-block:: console
+
+		make install T=$RTE_TARGET
+
+#. The compiled application will be located at:
+
+	.. code-block:: console
+
+		$RTE_SDK/$RTE_TARGET/app/flow-perf
+
+
+Running the Application
+=======================
+
+EAL Command-line Options
+------------------------
+
+Please refer to :doc:`EAL parameters (Linux) <../linux_gsg/linux_eal_parameters>`
+or :doc:`EAL parameters (FreeBSD) <../freebsd_gsg/freebsd_eal_parameters>` for
+a list of available EAL command-line options.
+
+
+Flow performance Options
+------------------------
+
+The following are the command-line options for the flow performance application.
+They must be separated from the EAL options, shown in the previous section, with
+a ``--`` separator:
+
+.. code-block:: console
+
+	sudo ./test-flow-perf -n 4 -w 08:00.0,dv_flow_en=1 --
+
+The command line options are:
+
+*	``--help``
+	Display a help message and quit.
