Test environment changes in VPP data plane performance tests: - - - Further characterization and optimizations of VPP vhost-user and VM test - methodology and test environment; - - - Tests with varying Qemu virtio queue (a.k.a. vring) sizes: - [vr256] default 256 descriptors, [vr1024] 1024 descriptors to - optimize for packet throughput; - - - Tests with varying Linux :abbr:`CFS (Completely Fair Scheduler)` - settings: [cfs] default settings, [cfsrr1] :abbr:`CFS (Completely Fair - Scheduler)` RoundRobin(1) policy applied to all data plane threads - handling test packet path including all VPP worker threads and all Qemu - testpmd poll-mode threads; - - - Resulting test cases are all combinations with [vr256,vr1024] and - [cfs,cfsrr1] settings; - - - For more detail see performance results observations section in - this report; - -#. Code updates and optimizations in CSIT performance framework: - - - Complete CSIT framework code revision and optimizations as descried - on CSIT wiki page `Design_Optimizations - `_. - - - For more detail see the :ref:`CSIT Framework Design ` section - in this report; - -#. Changes to CSIT driver for TRex Traffic Generator: - - - Complete refactor of TRex CSIT driver; - - - Introduction of packet traffic profiles to improve usability and - manageability of traffic profiles for a growing number of test - scenarios. - - - Support for packet traffic profiles to test IPv4/IPv6 stateful and - stateless DUT data plane features; - -#. Added VPP performance tests - - - **Linux Container VPP memif virtual interface tests** - - - VPP Memif virtual interface (shared memory interface) tests - interconnecting VPP instances over memif. VPP vswitch - instance runs in bare-metal user-mode handling Intel x520 NIC - 10GbE interfaces and connecting over memif (Master side) virtual - interfaces to another instance of VPP running in bare-metal Linux - Container (LXC) with memif virtual interfaces (Slave side). LXC - runs in a priviliged mode with VPP data plane worker threads - pinned to dedicated physical CPU cores per usual CSIT practice. - Both VPP run the same version of software. This test topology is - equivalent to existing tests with vhost-user and VMs. - - - **Stateful Security Groups** - - - New tests of VPP stateful security-groups a.k.a. acl-plugin - functionally compatible with networking-vpp OpenStack; - - - New tested security-groups access-control-lists (acl) - configuration variants include: [iaclNsl] input acl stateless, - [oaclNsl] output acl stateless, [iaclNsf] input acl stateful - a.k.a. reflect, [oaclNsf] output acl stateful a.k.a. reflect, - where N is number of access-control-entries (ace) in the acl. - - - Testing packet flows transmitted by TG: 100, 10k, 100k, always - hitting the last permit entry in acl. - - - **VPP vhost and VM tests** - - - New VPP vhost-user and VM test cases to benchmark performance of - VPP and VM topologies with Qemu and CFS policy combinations of - [vr256,vr1024] x [cfs,cfsrr1]; - - - Statistical analysis of repeatibility of results; - -Performance Improvements ------------------------- - -Substantial improvements in measured packet throughput have been observed in a -number of CSIT |release| tests listed below, with relative increase of -double-digit percentage points.

VPP PERFORMANCE TESTS + + - **Service density 2n-skx tests**: Added higher NF density tests with two + NFs' data-plane threads sharing a physical core. VPP IPv4 routing is now + used as a VNF payload similar to CNF tests. + + - **Soak Tests**: Optimized 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. See updated + :ref:`test_methodology` section for more details. + +#. TEST FRAMEWORK + + - **Qemu code refactor**: Complete code refactor of the key components of + QemuUtil.py and QemuManager.py (L1 and L2 KW counterparts). Added + implementation of kernel-image-kvm based VM replacing the previously used + NestedVM images. Added ability to run VPP as a payload in VNF. + + - **CSIT PAPI Support**: Continued conversion of CSIT VAT L1 keywords to + PAPI L1 KWs in CSIT using VPP Python bindings. Redesign of key components + of PAPI Executor and PAPI history. + + - **General Code Housekeeping**: Ongoing RF keywords optimizations, + removal of redundant RF keywords. + + - **Test suite generator**: Added capability to generate suites for + different NIC models as well as throughput search algorithm types. Uses + base tests suites as source. + + - **TOX verification**: Added verifications for test suite generator. + +#. PRESENTATION AND ANALYTICS LAYER + + - **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. + +.. raw:: latex + + \clearpage + +.. _vpp_known_issues: + +Known Issues +------------ + +List of known issues in |csit-release| for VPP performance tests: + ++----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+ +| # | JiraID | Issue Description | ++====+=========================================+==========================================================================================================+ +| 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520.
