+Speedup Multi-Core
+==================
+
+Speedup Multi-Core throughput graphs are generated by multiple
+executions of the same performance tests across physical testbeds hosted
+LF FD.io labs: 2n-skx, 3n-skx, 2n-clx, 3n-tsh, 2n-tx2, 2n-dnv, 3n-dnv.
+Grouped bars illustrate the 64B/78B packet throughput speedup ratio for
+2- and 4-core multi-threaded VPP configurations relative to 1-core
+configurations.
+
+Additional information about graph data:
+
+#. **Graph Title**: describes tested packet path, testbed topology,
+ processor model, NIC model, packet size used by data plane workers and
+ indication of VPP DUT configuration.
+
+#. **X-axis Labels**: number of cores.
+
+#. **Y-axis Labels**: measured Packets Per Second [pps] throughput
+ values.
+
+#. **Graph Legend**: lists CSIT test suites executed to generate graphed test
+ results.
