.. raw:: latex \clearpage .. _VPP_HDRH_Packet_Latency: Packet Latency ============== VPP latency results are generated based on the test data obtained from |csit-release| NDR-PDR throughput tests executed across physical testbeds hosted in LF FD.io labs: 3n-hsw, 3n-skx, 2n- skx, 2n-clx, 3n-dnv, 2n-dnv, 3n-tsh, 2n-tx2. Latency by percentile distribution plots are used to show packet latency percentiles at different packet rate load levels: i) No-Load latency streams only, ii) Low-Load at 10% PDR, iii) Mid-Load at 50% PDR and iv) High-Load at 90% PDR. Additional information about graph data: #. **Graph Title**: describes tested DUT packet path. #. **X-axis Labels**: percentile of packets. #. **Y-axis Labels**: measured one-way packet latency values in [uSec]. #. **Graph Legend**: list of latency tests at different packet rate load level. #. **Hover Information**: packet rate load level, stream direction (East-West, West-East), percentile, one-way latency. .. note:: Test results have been generated by `FD.io test executor vpp performance job 2n-skx`_, `FD.io test executor vpp performance job 3n-skx`_, `FD.io test executor vpp performance job 2n-clx`_, `FD.io test executor vpp performance job 2n-zn2`_, `FD.io test executor vpp performance job 3n-hsw`_, `FD.io test executor vpp performance job 3n-tsh`_ and `FD.io test executor vpp performance job 2n-tx2`_ with RF result files csit-vpp-perf-|srelease|-\*.zip `archived here <../../_static/archive/>`_. .. toctree:: :maxdepth: 3 l2 ip4 ip6 srv6 ip4_tunnels nat44 vm_vhost container_memif ipsec
