Jira Task Tracking
All CSIT release deliverables should be tracked in FDio CSIT Jira using one of the following Jira Epic categories:
Framework CI process Performance Device Methodology Telemetry Tools Presentation HoneyComb [Aarch64]https://jira.fd.io/browse/CSIT-1050
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. |
