Overlay networks are the de facto networking technique for providing flexible, customized connectivity among distributed containers in the cloud. However, overlay networks also incur non-trivial overhead due to its complexity, resulting in significant network performance degradation of containers. In this paper, we perform a comprehensive empirical performance study of container overlay networks which identifies unrevealed, important parallelization bottlenecks of the kernel network stack that prevent container overlay networks from scaling. Our observations and root cause analysis cast light on optimizing the network stack of modern operating systems on multi-core systems to more efficiently support container overlay networks in light of high-speed network devices.
