#. VPP PERFORMANCE TESTS
- - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: VPP performance
- test data is not included in this report version. This is due to
- the lower performance and behaviour inconsistency of these
- systems following the upgrade of processor microcode packages
- (skx ucode 0x2000064, clx ucode 0x500002c), done 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
- added in subsequent maintenance report version(s) once the issue
- is resolved. 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 now versioned, with ver. 1 associated
+ with CSIT rls1908 git branch as of 2019-08-21, and ver. 2
+ associated with CSIT rls2001 and master git branches as of
+ 2020-03-27.
+
+ - To identify performance changes due to VPP code changes from
+ v20.01.0 to v20.05.0, both have been tested in CSIT environment
+ ver. 2 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`.
#. TEST FRAMEWORK
- - **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.
-
- - **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.
-
- - **Test Suite Generator**: Added capability to generate suites for
- different drivers per NIC model including DPDK, AVF, RDMA.
- Extended coverage for all tests.
+ - **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.
-
#. 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`.
