VPP PERFORMANCE TESTS - - *MRR tests* - New Maximum Receive Rate tests measure the packet - forwarding rate under the maximum load offered by traffic - generator over a set trial duration, regardless of packet loss. - MRR tests are used for continuous performance trending and for - comparison between releases. + - **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 Chaining with SRv6* - New SRv6 (Segment Routing IPv6) proxy - tests measure performance of SRv6 Endpoint fronting SR-unaware - appliance via masquerading (End.AM), dynamic proxy (End.AD) or - static proxy (End.AS) SR functions. + - **Service density 2n-skx tests**: Added new NF density tests with + IPsec encryption between DUTs. -#. **Presentation and Analytics Layer** + - **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). - - *Performance trending* - Added continuous performance trending and - analysis. New Performance Trending and Performance Analysis jobs - executed regular throughput tests, with results being subsequently - analysed and trend and anomalies summarized and presented in VPP - Performance Dashboard and trendline graphs. + - **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. -#. **Test Framework Optimizations** + - **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. - - *Performance tests efficiency* - Qemu build/install optimizations, - warmup phase handling, vpp restart handling. Resulted in improved - stability and reduced total execution time by 30% for single pkt - size e.g. 64B/78B. + - **Mellanox MCX556A-EDAT tests**: Added tests with Mellanox + ConnectX5-2p100GE NICs in 2n-clx testbeds using VPP native rdma + driver. - - *General code housekeeping* - ongoing RF keywords optimizations, - removal of redundant RF keywords. + - **IPsec reconfiguration tests**: Added tests measuring the impact + of IPsec tunnels creations and removals. -Performance Changes -------------------- + - **Load Balancer tests**: Added VPP performance tests for Maglev, + L3DSR (Direct Server Return), Layer 4 Load Balancing NAT Mode. -Relative performance changes in measured packet throughput in CSIT -|release| are calculated against the results from CSIT |release-1| -report. Listed mean and standard deviation values are computed based on -a series of the same tests executed against respective VPP releases to -verify test results repeatibility, with percentage change calculated for -mean values. Note that the standard deviation is quite high for a small -number of packet throughput tests, what indicates poor test results -repeatability and makes the relative change of mean throughput value not -fully representative for these tests. The root causes behind poor -results repeatibility vary between the test cases. +#. TEST FRAMEWORK -NDR Changes -~~~~~~~~~~~ + - **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. -NDR small packet throughput changes between releases are available in a -CSV and pretty ASCII formats: + - **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.
