.. raw:: latex \clearpage Packet Latency ============== DPDK Testpmd and L3fwd 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-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. For more details, see :ref:`latency_methodology`. 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 are stored in `build logs from FD.io dpdk performance job 2n-skx`_, `build logs from FD.io dpdk performance job 2n-clx`_, `build logs from FD.io dpdk performance job 3n-skx`_, `build logs from FD.io dpdk performance job 2n-zn2`_, `build logs from FD.io dpdk performance job 3n-tsh`_ and `build logs from FD.io dpdk performance job 2n-tx2`_ with RF result files csit-dpdk-perf-|srelease|-\*.zip `archived here <../../_static/archive/>`_. .. toctree:: :maxdepth: 3 2n-skx-xxv710 3n-skx-xxv710 2n-clx-xxv710 2n-zn2-xxv710 3n-tsh-x520 .. 2n-tx2-xl710
