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.
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 3n-hsw`_ and
`FD.io test executor vpp performance job 3n-tsh`_ with RF
result files csit-vpp-perf-|srelease|-\*.zip
`archived here <../../_static/archive/>`_.
