Agenda
Awesome presentation
- Describe VSPERF
- Describe the Experimental Study
- Thanks to: <see slides>
Minutes
Work in progress 8 months+, thanks to many people outside the project who helped with details of setup
Looking for feedback on tests we should run, in addition to whaat has been done (20+ plots - will discuss results in bullets today to save time).
Background on VSPERF project - started in 2014 in OPNFV. Will re-name project soon. beyond test automation development, we conduct Experiments and feedback the expereince and features into the project code/framework.
Auto cluster, test, and test runs for the K8s cases.
Cluster: Ansible Role, Hosts, CNIs (Multus) - helps from Student Volunteers! (Parth and Emmanuel)
Described test details / configuration in the slides
THE EXPERIMENTS:
- Question what are the K8s performance gaps?
- For DPDK based multi-interface pods, what are the CNI plugin options, and how do they perform?
- What are teh Setup Challenges?
- OVS-DPDK, VPP, and SR-IOV: How do they compare with various options:
- VPP with memif outperform vhost user
- Need Binary Search WITH Loss-verification (ETSI NFV TST009)
- Also run RFC 2544 Back 2 Back Frame Benchmark for buffer size measurement (see Internet Draft that updates 2544)
- CPU Count -
- NUMA placement -
NEXT STEPS
- OVS -DPDK with memif
- others
- HW Traffic Generator is most reliable.
- Other CNIs? requests (and help appreciated).
Cedric Ollivier - comments on results, need separate session on deploying the tests in other labs
A: we are using the X-testing framework with VSPERF, need a separate session to cover this. Also sharing the results with testdb so that the results are more widely available.
