Explore the performance characteristics of userspace and kernel-space datapaths in container networking through this 14-minute conference talk from DevConf.US 2025. Learn about OpenShift's default container datapath implementation using veth pairs connected to an OVS bridge with kernel-space networking, and discover how the introduction of DPDK and VDUSE (vDPA devices in userspace) enables userspace datapath solutions that unlock DPDK benefits for containerized workloads. Examine the technical architecture of the VDUSE OVS-DPDK userspace datapath solution being implemented in OpenShift, and analyze real-world benchmark results comparing userspace and kernel-space datapaths across key performance metrics including latency, throughput, and packets per second (PPS). Gain insights into how these networking solutions compare in practical containerized environments and understand the performance implications of choosing between userspace and kernel-space approaches for container networking in OpenShift deployments.
