1. Throughput Speedup Analysis - Multi-Core Speedup Ratio
    a. subset of existing performance tests with 1core, 2core, 4core;
        - graph type: grouped bars - see examples in performance_analysis_sw_data_planes_dec21_2017.pdf;
        - graph X-axis: (testcase index, number of cores);
        - graph Y-axis: speedup factor (normalized to Mpps throughput for 64B on 1 core, showed as 1);
            - use mean Mpps throughput values;
    b. avoid interface, NIC, PCIe I/O limit - verify linearity of speedup;
        - 40GE xl710;
    c. baseline tests first;
        - L2 Ethernet Switching: l2xcbase, l2bdbasemaclrn;
        - IPv4 Routed-Forwarding: ip4base;
        - IPv6 Routed-Forwarding: ip6base;
    d. scale tests next:
        - L2 Ethernet Switching: l2bdscale10k, 100k, 1M;
        - IPv4 Routed-Forwarding: ip4scale20k, 200k, 2M;
        - IPv6 Routed-Forwarding: ip6scale20k, 200k, 2M;
    e. baseline features next:
        - L2 Ethernet Switching: l2bdbasemaclrn-iacl50sl, iacl50sf, oacl50sl, oacl50sf;
        - IPv4 Routed-Forwarding: ip4base-iacl50sl, iacl50sf, oacl50sl, oacl50sf;
    f. overlay tests next:
        - IPv4 Overlay Tunnels: ip4vxlan-l2xcbase, ip4vxlan-l2bdbasemaclrn, ip4lispip4-ip4base;
        - IPv6 Overlay Tunnels: ip6lispip4-ip4base, ip6lispip6-ip6base;
