This testing is focused on functional and performance regressions. The results -are posted to `CSIT Test Report <https://docs.fd.io/csit/master/report/>`_. - -For more about CSIT checkout the following links: - -* `CSIT Code Documentation <https://docs.fd.io/csit/master/doc/overview.html>`_ -* `CSIT Test Overview <https://docs.fd.io/csit/master/report/introduction/overview.html>`_ -* `VPP Performance Dashboard <https://docs.fd.io/csit/master/trending/introduction/index.html>`_ - - -CSIT Packet Throughput examples -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - -Following are pointers to a few of the CSIT test reports. The test's titles read like this: - -<packet size>-<number of threads><number of cores>-<test>-<interface type> - -For example the test with the title 64b-2t1c-l2switching-base-i40e is the -test that does l2 switching using 64 byte packets, 2 threads, 1 core using an i40e -interface. - -Here are a few examples: - -* `L2 Ethernet switching <https://docs.fd.io/csit/master/report/vpp_performance_tests/packet_throughput_graphs/l2.html>`_ -* `IPv4 Routing <https://docs.fd.io/csit/master/report/vpp_performance_tests/packet_throughput_graphs/ip4.html>`_ -* `IPv6 Routing <https://docs.fd.io/csit/master/report/vpp_performance_tests/packet_throughput_graphs/ip6.html>`_ - - -Trending Throughput Graphs -^^^^^^^^^^^^^^^^^^^^^^^^^^ - -These are some of the trending packet throughput graphs from the CSIT `trending dashboard <https://docs.fd.io/csit/master/trending/introduction/index.html>`_. **Please note that**, performance in the trending graphs will change on a nightly basis in line with the software development cycle: - -* `L2 Ethernet Switching Trending <https://docs.fd.io/csit/master/trending/trending/l2.html>`_ -* `IPv4 Routing Trending <https://docs.fd.io/csit/master/trending/trending/ip4.html>`_ -* `IPv6 Routing Trending <https://docs.fd.io/csit/master/trending/trending/ip6.html>`_ |
