5 .. _VPP_HDRH_Packet_Latency:
10 VPP latency results are generated based on the test data obtained from
11 |csit-release| NDR-PDR throughput tests executed across physical
12 testbeds hosted in LF FD.io labs: 3n-hsw, 3n-skx, 2n- skx, 2n-clx,
13 3n-dnv, 2n-dnv, 3n-tsh.
15 Latency by percentile distribution plots are used to show packet latency
16 percentiles at different packet rate load levels: i) No-Load latency
17 streams only, ii) Low-Load at 10% PDR, iii) Mid-Load at 50% PDR and iv)
20 Additional information about graph data:
22 #. **Graph Title**: describes tested DUT packet path.
24 #. **X-axis Labels**: percentile of packets.
26 #. **Y-axis Labels**: measured one-way packet latency values in [uSec].
28 #. **Graph Legend**: list of latency tests at different packet rate load
31 #. **Hover Information**: packet rate load level, stream direction
32 (East-West, West-East), percentile, one-way latency.
