+L3fwd
+=====
This section includes summary graphs of L3FWD Phy-to-Phy performance with packet
-routed forwarding measured at 50% of discovered NDR throughput rate. Latency is
+routed forwarding measured at 100% of discovered NDR throughput rate. Latency is
reported for L3FWD running in multiple configurations of L3FWD pmd thread(s),
a.k.a. L3FWD data plane thread(s), and their physical CPU core(s) placement.
-L3FWD packet latency - running in configuration of **one worker thread (1t) on one
-physical core (1c)** - is presented in the figure below.
+CSIT source code for the test cases used for plots can be found in
+`CSIT git repository <https://git.fd.io/csit/tree/tests/dpdk/perf?h=rls1810>`_.
