Traditional NFVi dataplane performance testing rarely focuses on (availability, consumption) dark resources such as CPU Cache and Memory Bandwidth. Much of the Quality of Service fine tuning often leads to oversubscription ending up with shared resource contention often termed as noisy neighbor effects. We present the methodology and test scenarios using open source solutions - OPNFV-VSPERF Framework, Collectd monitoring solution, Stress-NG workload generator and Resource Management client for (a) analyzing the performance impact due to presence of noisy neighbors and (b) controlling resources like Last Level Cache (LLC) for optimal performance. This talk was presented at recent Open Source Summit.
