#. VPP PERFORMANCE TESTS
- - **Service density 2n-skx tests**: Network Function Virtualization (NFV)
- service density tests focus on measuring total per server throughput at
- varied NFV service *packing* densities with vswitch providing host
- dataplane. The goal is to compare and contrast performance of a shared
- vswitch for different network topologies and virtualization technologies,
- and their impact on vswitch performance and efficiency in a range of NFV
- service configurations.
-
- - **Experimental Soak Tests**: Added performamce soak tests framework
- code for extended time duration tests and throughput discovery
- at given PLR and at give total test time e.g. minutes, hours,
- days, weeks, months, years. See updated
- :ref:`test_methodology` section for more details.
+ - **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, both have been tested in CSIT environment
+ ver. 2 and compared against each other. 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.
#. TEST FRAMEWORK
- - **Container code optimizations**: Optimized container library allows to
- run containre_memif tests faster.
+ - **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**: Continue converting existing VAT L1 keywords to
- PAPI L1 KWs in CSIT using VPP Python bindings. Required for migrating away
- from VAT.
+ - **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.
- **General Code Housekeeping**: Ongoing RF keywords optimizations,
- removal of redundant RF keywords.
+ 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
+ - **Graphs layout improvements**: Improved performance graphs layout
for better readibility and maintenance: test grouping, axis
labels, descriptions, other informative decoration.
-#. MISCELLANEOUS
-
- - **2n-dnv Tests (3rd Party)**: Published performance tests for 2n-
- dnv (2-Node Atom Denverton) from 3rd party testbeds running FD.io
- |csit-release| automated testing code.
- Only graphs for Packet Throughput and Speedup Multi-core and not
- for Packet Latency were published as there are no results for Packet
- Latency available.
+ - **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`.
