#. VPP PERFORMANCE TESTS
- - **BMRR Throughput**: MRR (Maximum Receive Rate) test code has been
- updated with a configurable burst MRR parameters: trial duration
- and number of trials in a single burst. Enables a new Burst MRR
- (BMRR for short) methodology for more precise performance
- trending. See updated :ref:`performance_test_methodology` section
- for more details.
-
- - **2n-skx tests**: Added performamce tests for 2n-skx (2-Node Xeon
- Skylake) testbeds: focus on baseline and scale tests, including
- VM vhost and Container memif tests.
-
- - **3n-skx tests**: Added performamce tests for 3n-skx (3-Node Xeon
- Skylake) testbeds: VM vhost and Container memif tests.
-
- - **VXLAN Scale Tests**: Added performamce tests for VXLAN scale with
- dot1q and VPP L2BD.
-
- - **AVF Driver Tests**: Added performamce tests for i40e AVF driver
- on VPP, no DPDK required.
-
- - **QAT**: Fixed reoccuring issues with QAT crypto accelerator cards.
-
- - **VM Vhost Virtio Params Combinations**: Added performance tests
- for VM vhost with different virtio parameters combinations:
- indirect buffers, mergeable buffers.
-
- - **K8s/Ligato in Trending**: Added K8s/Ligato Container memif tests
- to daily trending.
+ - **Intel Xeon 2n-skx, 3n-skx 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), done as part of updating Ubuntu 18.04 LTS kernel
+ version. Tested VPP and DPDK applications (L3fwd) are affected.
+ Skx test data will be added in subsequent maintenance report
+ version(s) once the issue is resolved. See
+ :ref:`vpp_known_issues`.
+
+ - **Intel Xeon 2n-clx testbeds**: VPP performance test data is now
+ included in this report, after resolving the issue of lower
+ performance and behaviour inconsistency of these systems due to
+ the Linux kernel driven upgrade of processor microcode packages
+ to 0x500002c. The resolution is to use latest SuperMicro BIOS 3.2
+ (for X11DPG-QT motherboards used) that upgrades processor
+ microcode to 0x500002c, AND NOT kernel provided ucode package as
+ it does put system into sub-optimal state. Subset of 2n-clx VPP
+ tests are failing due to clx system behaviour change: i) all ip4
+ tests with xxv710 and avf driver and ii) some cx556a rdma tests.
+ 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
- - **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:`performance_test_methodology` section for more details.
-
- - **Trending Tests BMRR**: Used new Burst MRR (BMRR) tests for daily
- trending.
+ - **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.
- - **Per VPP Patch Performance Checks**: Per VPP gerrit patch vs.
- parent performance tests, anomaly detection and no verify voting
- (-1/0/+1) yet. Manual trigger only. Not "marketed" to FD.io
- community yet to avoid excessive LFN FD.io physical performance
- testbed blocking.
+ - **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.
- - **Patch-on-Patch Infra**: Added capability to run performance tests
- using CSIT gerrit patch code testing VPP gerrit patch code, i.e.
- before any VPP and/or CSIT code is merged into git branch.
-
- - **CSIT PAPI Support**: Initial implementation of PAPI L1 KWs in
- CSIT using VPP Python bindings. Required for migraing away from
- VAT. Very few L1 KWs implemented ("show version", "show
- interfaces").
+ - **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.
-
-#. PRESENTATION AND ANALYTICS LAYER
+ removal of redundant RF keywords and aligning of suite/test
+ setup/teardowns.
- - **Graphs Layout Improvements**: Improved performance graphs layout
- for better readibility and maintenance: test grouping, axis
- labels, descriptions, other informative decoration. Master report
- generated. 744 graphs(!)
+#. 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>`_].
- - **Performance Trending**: Further improvements of continuous
- performance trending, anomaly detection and analysis.
+ - **New Intel Xeon Cascadelake Testbeds**: Added performance tests
+ for 2-Node-Cascadelake (2n-clx) testbeds with x710, xxv710 and
+ cx556a-edat NIC cards.
-#. MISCELLANEOUS
+#. PRESENTATION AND ANALYTICS LAYER
- - **3n-dnv Tests (3rd Party)**: Published performance tests for 3n-
- dnv (3-Node Atom Denverton) from 3rd party testbeds running FD.io
- |csit-release| automated testing code.
+ - **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`.
