Jira Task Tracking

All CSIT release deliverables should be tracked in FDio CSIT Jira using one of the following Jira Epic categories:

  1. to be added

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 QEMU;

iii) Push vpp-dev to Ubuntu 18.04.

Arm testbeds Introduce Arm performance tests.
Atom testbeds Introduce Denverton and Rangeley performance tests.
Better vhost, memif coverage Produce more complete test data for NFV service density:

i) Scaled-out Vhost-user/VM and Memif/Container tests; ii) Test the same packet paths and NF topologies: service chains, service pipelines;

iii) See if we can isolate the actual cost of Vhostuser-virtio and Memif-Memif virtual interfaces based on the test and system telemetry.

iv) Test with VM and Containers running on a single Processor (single socket) with no core oversubscription and with.

v) Extend the test over two Processors to quantify impact of UPI latency (and bandwidth).

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.

Trending Improved Detection Make trending job use new Burst MRR trending tests for better anomaly detection:

i) Currently postponed, as the algorithm detects performance changes not related to VPP code.

ii) We need heavy workarounds or way more predictable SUT behavior.

More VPP telemetry reported and analysed API based consumption of VPP telemetry including existing general counters, and future extended per node counters.
Evolve throughput search Build upon MLRsearch and PLRsearch experience vs. ordinary binary search:

i) Compare MLRsearch with PLRsearch soak test results.

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-18.10 results data.
