We will present our methodology and test design for measuring performance of OVS.
We use a combination of Ansible and other open-source tools for orchestrating configuration management, organizing tests, and storing results.
We use this framework to routinely run repeatable, reliable performance tests using both software tools (e.g. netperf in a VM) and hardware tools (e.g. RFC2544 tests with Spirent).
We will discuss how to configure the system (Linux and OVS) for achieving maximum performance on multicore machines, and how to tune to get consistent results. Consistent numbers are important to be able to detect performance regressions across different builds.
We will present results to compare performance of KVM OVS with different data paths.
