Hi,
A draft version of CSIT-1908 test and benchmarking report is available
on the CSIT master report link:
https://docs.fd.io/csit/master/report/index.html
Most of the selected benchmarking tests have been completed including:
- All Xeon Skylake and Haswell NDR and PDR tests - all in draft report.
- Most of Atom/Denverton NDR and PDR tests - to be added to draft report.
- Most of Arm/Taishan NDR and PDR tests - to be added to draft report.
Comparison tables show some Skylake NDR/PDR throughput regressions and
progressions vs. CSIT-1904:
-
https://docs.fd.io/csit/master/report/vpp_performance_tests/comparisons/current_vs_previous_release.html
Their latest analysis is tracked in the two CSIT gerrit commits:
- csit1908_perf_analysis_2n_skx.md: https://gerrit.fd.io/r/c/csit/+/21637/
- csit1908_perf_analysis_3n_skx.md: https://gerrit.fd.io/r/c/csit/+/21641/
Most have been root caused to CSIT and are being addressed in CSIT
before CSIT-1908 report is published on Wednesday 04-Sep.
Two VPP packet paths, l2 bridge-domain and iacl statefull&stateless have
suspected cause: *vpp binary code change affecting throughput*.
Any assistance with these two is appreciated.
Cheers,
-Maciek
