Benchmark results of Kubernetes network plugins (CNI) over 10Gbit/s network

Kubernetes is a great orchestator for containers. But it does not manage network for Pod-to-Pod communication. This is the mission of Container Network Interfaces (CNI) plugins which are a standardized way to achieve network abstraction for container clustering tools (Kubernetes, Mesos, OpenShift, etc.) But here is the point: what are the differences between those CNIs? Which one has the best performance? Which one is the leanest? This article is showing the results of a benchmark I’ve conducted on 10Gbit/s network.
