Release Deliverables

Name	Status	Jira Category	Description
3n-skx Tests	Done	1810-Test	Add performamce tests for 3n-skx (3-Node Xeon Skylake) testbeds: VM vhost and Container memif tests.
2n-skx Tests	Done	1810-Test	Add performamce tests for 2n-skx (2-Node Xeon Skylake) testbeds: focus on baseline and scale tests.
VXLAN Scale Tests	Done	1810-Test	Add performamce tests for VXLAN scale with dot1q and l2bd.
AVF Driver Tests	Done	1810-Test	Add performamce tests for i40e AVF driver on VPP, DPDK-free.
QAT	Done	1810-Test	Fix reoccuring issues with QAT crypto accelerator cards.
VM Vhost Virtio Params Combinations	Done	1810-Test	Add performance tests for VM vhost with different virtio parameters combinations: indirect buffers, mergeable buffers.
Soak Tests Experimental	WIP	1810-Framework	Add soak performamce tests infrastructure for extended test duration and throughput discovery at given PLR and total long soak time e.g. minutes, hours, days.
VPP_Device	WIP	1810-Framework	Container based functional VPP device tests: CI/CD system design integrated into LF, running on 1-Node testbeds (1n-skx, 1n-arm). Relying on VF+dot1q for external loopback cable packet passing. Focus on few baseline tests.
VPP_Path	Open	1810-Framework	Continuing migration of CSIT VIRL tests to VPP-make_test VPP integration tests for functional acceptance of VPP feature path(s) driven by use case(s). See P1 and P2 markup in CSIT_VIRL migration progress.
Trending Improved Detection	Done	1810-PAL	Make trending job use new Burst MRR trending tests for better anomaly detection.
Trending Tests BMRR	Done	1810-Framework	Use new Burst MRR tests for daily trending.
K8s/Ligato in Trending	Done	1810-Test	Add K8s/Ligato Container memif tests to daily trending.
Per VPP Patch Performance Checks	WIP	1810-Framework	Per VPP gerrit patch vs. parent performance tests, anomaly detection and voting (-1/0/+1).
Patch-on-Patch Infra	WIP	1810-Framework	Add capability to run performance tests using CSIT gerrit patch code testing VPP gerrit patch code, i.e. before any code is merged into git branch.
CSIT PAPI Support	WIP	1810-Framework	Implementation of PAPI L1 KWs in CSIT. Required for migrating away from VAT.
Graphs Layout Improvements	WIP	1810-PAL	Improve performance graphs layout for better readibility and maintenance: test grouping, axis labels, descriptions, other informative decoration.
Clock cycles per VPP node into CSIT-PAL	Open	1810-PAL	Use the new VPP stats infra available via PAPI to retrieve runtime counters instead of using "show run". Blocked by no PAPI support in FD.io CSIT.

Multi-Release Work Areas

Work Area	Description
Xeon Skx testbeds	Make Skylake performance test coverage complete: i) Boost tests in 2-Node setups, complete 3-Node setups; ii) Complete Memif/Container and Vhost-user/VM with latest greatest QEMU etc; iii) Push vpp-dev to Ubuntu 18.04.
Arm testbeds	Introduce Arm performance tests. Machines
Atom testbeds	Introduce Atom performance tests.
Better vhost, memif coverage	Make CSIT produce more complete test data for scaled-out Vhost-user/VM and Memif/Container: i) Complete same packet paths and topologies for a low number of VMs and Containers, then scale-up VM and Container numbers; ii) See if we can isolate the actual cost of Vhostuser-virtio and Memif-Memif virtual interfaces based on the test and system telemetry.
VPP per patch performance tests	Productise per VPP patch performance tests with change detection, prepare for voting: i) Improve detection accuracy and precision; ii) Nail down current results variance; iii) Apply improvements to continuous trending and (future) git auto-bisection.
Evolve throughput search	Build upon MLRsearch experience vs. ordinary binary search: i) New POC for extended soak test for validating NDR (zero packet-loss-ratio PLR) and(?) PDR (non-zero PLR).
General enhancements	General CSIT and VPP performance test and infrastructure enhancements: i) Productize VPP_Device container-based functional tests in 1-Node Skylake testbeds, assist with the same for Arm; ii) Add proper packet latency measurements with T-Rex HDRhistogram, push T-Rex to productize HDRh'gram; iii) Start using the new VPP stats infra for per test counters and "gauges" collection incl. "show runtime", instead of VPP show CLI; iv) Start migration from VAT to VPP Python API; v) Nail down "broken"/not-performing VPP data plane feature arcs (incl. multi-threading) indicated by CSIT-18.07 results data.
