#. VPP PERFORMANCE TESTS
- - **Intel Xeon 2n-skx, 3n-skx testbeds**: VPP performance test data
- is now included in this report version. Due to substantial impact
- of test environment changes (applied during the CSIT-2001
- development cycle) on the performance of VPP software, a new
- approach to performance comparison and progression/regression
- root cause analysis (RCA) has been applied.
-
- - CSIT test environment is now versioned, with ver. 1 associated
- with CSIT rls1908 git branch as of 2019-08-21, and ver. 2
- associated with CSIT rls2001 git branch as of 2020-03-27.
-
- - To identify performance changes due to CSIT test environment
- changes from ver. 1 to ver. 2, VPP v19.08.1 has been re-tested in
- ver. 2 and compared against the past results obtained with
- testing in ver. 1. Separate RCA1 analysis has been applied to
- this part. See :ref:`vpp_compare_current_vs_previous_release` and
- :ref:`vpp_known_issues`.
-
- - To identify performance changes due to VPP code changes from
- v19.08.1 to v20.01.0, the latter has been tested in CSIT
- environment ver. 2 and compared against the former tested in CSIT
- environment ver. 1. Separate RCA2 analysis has been applied to
- this part. See :ref:`vpp_compare_current_vs_previous_release` and
- :ref:`vpp_known_issues`.
-
- - **Intel Xeon 2n-clx testbeds**: VPP performance test data is now
- included in this report. See :ref:`vpp_known_issues`.
-
- - **Service density 2n-skx tests**: Added new NF density tests with
- IPsec encryption between DUTs.
-
- - **AVF tests**: Full test coveraged based on code changes in CSIT
- core layer (driver/interface awareness) and generated by suite
- generator (Intel Fortville NICs only).
-
- - **Hoststack tests**: Major refactor of VPP Hoststack TCP/IP
- performance tests using WRK generator talking to the VPP HTTP
- static server plugin measuring connections per second and
- requests per second. Added new iperf3 with LDPreload tests,
- iperf3/LDPreload tests with packet loss induced via the VPP NSIM
- (Network Simulator) plugin, and QUIC/UDP/IP transport tests.
- All of the new tests measure goodput through the VPP Hoststack
- from client to server.
-
- - **Latency HDRHistogram**: Added High Dynamic Range Histogram
- latency measurements based on the new capability in TRex traffic
- generator. HDRH latency data presented in latency packet
- percentile graphs and in detailed results tables.
-
- - **Mellanox CX556A-EDAT tests**: Added tests with Mellanox
- ConnectX5-2p100GE NICs in 2n-clx testbeds using VPP native rdma
- driver.
-
- - **IPsec reconfiguration tests**: Added tests measuring the impact
- of IPsec tunnels creations and removals.
-
- - **Load Balancer tests**: Added VPP performance tests for Maglev,
- L3DSR (Direct Server Return), Layer 4 Load Balancing NAT Mode.
+ - CSIT test environment is versioned, see
+ :ref:`test_environment_versioning`.
-#. TEST FRAMEWORK
+ - To identify performance changes due to VPP code changes from
+ v20.05.0 to v20.09.0, both have been tested in CSIT environment
+ ver. 5 and compared against each other. All substantial
+ progressions has been marked up with RCA analysis. See
+ :ref:`vpp_compare_current_vs_previous_release` and
+ :ref:`vpp_known_issues`.
+
+ - **NAT44 tests**: Adapted existing and added new tests.
+
+ - Refactored NAT44 deterministic mode (nat44det) tests to use separate
+ det44 vpp plugin and to use the same scheme of inside and outside
+ addresses and ports, as used in new NAT44 endpoint-dependent mode tests.
- - **CSIT Python3 support**: Full migration of CSIT from Python2.7 to
- Python3.6. This change includes library migration, PIP dependency
- upgrade, CSIT container images, infrastructure packages
- ugrade/installation.
+ - Added new NAT44 endpoint-depended mode uni-directional (nat44ed-udir)
+ tests that measure packet throughput in one direction with usage of TRex
+ in stateless mode.
- - **CSIT PAPI support**: Finished conversion of CSIT VAT L1 keywords
- to PAPI L1 KWs in CSIT using VPP Python bindings (VPP PAPI).
- Redesign of key components of PAPI Socket Executor and PAPI
- history. Due to issues with PAPI performance, VAT is still used
- in CSIT for all VPP scale tests. See known issues below.
+ - Added new NAT44 endpoint-dependent mode CPS tests that measure
+ connections per second with usage of TRex in stateful mode.
+ NOTE: CPS measurement data will be added in two weeks.
- - **Test Suite Generator**: Added capability to generate suites for
- different drivers per NIC model including DPDK, AVF, RDMA.
- Extended coverage for all tests.
+ - **IPSec async mode tests**: Added VPP performance tests for async crypto
+ engine.
+
+ - **AMD 2n-zn2 testbed**: New physical testbed type installed in FD.io CSIT,
+ VPP performance data will be added in upcoming weeks.
+
+#. TEST FRAMEWORK
+
+ - **TRex ASTF**: Added capability to run TRex in advanced stateful mode.
+
+ - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
+ still used in CSIT for all VPP scale tests. See known issues below.
- **General Code Housekeeping**: Ongoing RF keywords optimizations,
removal of redundant RF keywords and aligning of suite/test
setup/teardowns.
-#. TEST ENVIRONMENT
-
- - **TRex Fortville NIC Performance**: Received FVL fix from Intel
- resolving TRex low throughput issue. TRex per FVL NIC throughput
- increased from ~27 Mpps to the nominal ~37 Mpps. For detail see
- `CSIT-1503 <https://jira.fd.io/browse/CSIT-1503>`_ and `TRex-519
- <https://trex-tgn.cisco.com/youtrack/issue/trex-519>`_].
-
- - **New Intel Xeon Cascadelake Testbeds**: Added performance tests
- for 2-Node-Cascadelake (2n-clx) testbeds with x710, xxv710 and
- cx556a-edat NIC cards.
+ - **Intel E810CQ 100G NIC**: Added configuration for Intel E810CQ 100G NIC.
+ No tests run for this NIC as it is not present in FD.io CSIT lab yet.
#. PRESENTATION AND ANALYTICS LAYER
- - **Graphs layout improvements**: Improved performance graphs layout
- for better readibility and maintenance: test grouping, axis
- labels, descriptions, other informative decoration.
-
- - **Latency graphs**: Min/Avg/Max group bar latency graphs are
- replaced with packet latency percentile distributon at different
- background packet loads based on TRex latency hdrhistogram
- measurements.
-
-..
- // Alternative Note for 1st Bullet when bad microcode Skx, Clx results are published
- - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: VPP performance
- test data is included in this report version, but it shows lower
- performance and behaviour inconsistency of these systems
- following the upgrade of processor microcode packages (skx ucode
- 0x2000064, clx ucode 0x500002c) as part of updating Ubuntu 18.04
- LTS kernel version. Tested VPP and DPDK applications (L3fwd) are
- affected. Skx and Clx test data will be corrected in subsequent
- maintenance report version(s) once the issue is resolved. See
- :ref:`vpp_known_issues`.
+ - **Graphs improvements**: Added possibility to use Gbps on Y-axis in
+ Packet Throughput and Speedup Multi-Core graphs, added unidirectional
+ mode to the Latency graphs.

-| | <https://jira.fd.io/browse/VPP-1677>`_ | VPP crashes very often in case that NAT44 is configured and it has to process IP4 jumbo frames (9000B). |
+| 3 | `CSIT-1763 | Adapt ramp-up phase of nat44 tests for different frame sizes. |
+| | <https://jira.fd.io/browse/CSIT-1763>`_ | Currently ramp-up phase rate and duration values are correctly set for tests with 64B frame size. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 5 | `CSIT-1591 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
-| | <https://jira.fd.io/browse/CSIT-1499>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |

+| | <https://jira.fd.io/browse/CSIT-1671>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
+| +-----------------------------------------+ The usual PAPI library spends too much time parsing arguments, so even with async processing (hundreds of |
+| | `VPP-1763 | commands in flight over socket), the VPP configuration for large scale tests (millions of messages) takes |
+| | <https://jira.fd.io/browse/VPP-1763>`_ | too long. |

+| | <https://jira.fd.io/browse/VPP-1934 >`_ | In case of i40e -based interface (e.g Intel x700 series NIC) is bound to kernel driver (i40e) and is in |
+| | | state "no-carrier" (<NO-CARRIER,BROADCAST,MULTICAST,UP>) because previously it was disabled via |
+| | | "I40E_AQ_PHY_LINK_ENABLED" call, then VPP during initialization of AVF interface is not re-enabling |
+| | | interface link via i40e driver to up. |
