Attendees: rhallisey, 

Agenda:

• Move to bi-weekly schedule

• 1.36 saw a regression for vmi create to run performance

• Issue to address the regression - https://github.com/kubevirt/kubevirt/pull/18800

• Pre download virt-launcher images onto the nodes. Reduce performance variance from external (no virt control plane) factors

• Prove Alpha feature performance for several weeks before graduating to beta

• Catch the perf regression before moving to beta

• New periodic test with alpha features enabled?

• Define an alpha to beta criteria for performance

• Beta flag performance - https://github.com/kubevirt/kubevirt/pull/17405

• Patch Nodes count VMI Doubles from 12 to 26

• avgVirtAPIMemUsage/maxVirtAPIMemUsage went up: Avg up from 140MB to 150MB and Max up from 170MB to 180MB
