#. VPP PERFORMANCE TESTS
- - **Service density 2n-skx tests**: Added higher NF density tests with
- IPSec encencryption between DUTs.
-
- - **AVF tests**: Full test coveraged based on code changes in CSIT core
- layer (driver/interface awareness) and generated by suite generator
- (Fortville NICs only).
-
- - **Hoststack TCP/IP tests**: Major refactor of Hoststack TCP
+ - **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.
+ 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
+ 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
- - **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 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
+ - **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 and aligning of suite/test
setup/teardowns.
#. 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.
+ - **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`.

List of known issues in |csit-release| for VPP performance tests:

-| 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520. DPDK reporting rx-errors, indicating L1 issue. |
-| | <https://jira.fd.io/browse/CSIT-570>`_ | Suspected issue with HW combination of X710-X520 in LF testbeds. Not observed outside of LF testbeds. |
-+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
-| 2 | `VPP-662 | 9000B packets not supported by NICs VIC1227 and VIC1387. |

-+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
-| 4 | `VPP-1677 | 9000B ip4 nat44: VPP crash + coredump. |
-| | <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). |
-+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
-| 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. |
-| +-----------------------------------------+ |
-| | `VPP-1763 | |

-+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
-| 6 | `VPP-1675 | IPv4 IPSEC 9000B packet tests are failing as no packet is forwarded. |
-| | <https://jira.fd.io/browse/VPP-1675>`_ | Reason: chained buffers are not supported. |
-+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
-| 7 | `CSIT-1593 | IPv4 AVF 9000B packet tests are failing on 3n-skx while passing on 2n-skx. |
