6 .. _throughput_speedup_multi_core:
11 Speedup Multi-Core throughput graphs are generated by multiple
12 executions of the same performance tests across physical testbeds hosted
13 LF FD.io labs: 3n-hsw, 2n-skx, 2n-skx. Grouped bars illustrate the
14 64B/78B packet throughput speedup ratio for 2- and 4-core multi-
15 threaded VPP configurations relative to 1-core configurations.
17 Additional information about graph data:
19 #. **Graph Title**: describes tested packet path, testbed topology,
20 processor model, NIC model, packet size used by data plane workers and
21 indication of VPP DUT configuration.
23 #. **X-axis Labels**: number of cores.
25 #. **Y-axis Labels**: measured Packets Per Second [pps] throughput
28 #. **Graph Legend**: lists CSIT test suites executed to generate graphed test
31 #. **Hover Information**: lists number of runs executed, specific test
32 substring, mean value of the measured packet throughput, calculated perfect
33 throughput value, difference between measured and perfect values and
34 relative speedup value.
38 Test results have been generated by
39 `FD.io test executor vpp performance job 3n-hsw`_,
40 `FD.io test executor vpp performance job 3n-skx`_ and

44 Required per test case data set size is **10**, but for VPP tests
45 the actual size varies per test case and is <=10.
