#. 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`.
+ - **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 TCP/IP tests**: Major refactor of VPP Hoststack TCP/IP
+ - **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 iperf3 tests with LDPreload.
+ 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 MCX556A-EDAT tests**: Added tests with Mellanox
+ - **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.
+ - **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
- **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.
+ 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).
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.
