OpenStack Neutron with ML2 OVS has always been a challenging component in terms of performance and scalability. However, in recent releases, several enhancements and bug-fixes have resulted in significant improvements in overall reliability, performance and scalability of Neutron. In this presentation, we will share the results of our testing (both control-plane and data-plane) at large scale and provide a detailed data-driven analysis that explores the true scale limits and bottlenecks of Neutron.
