Deep Dive into Service Mesh Data Plane Performance and Tuning

Dive deep into the performance and tuning aspects of service mesh data planes in this 38-minute conference talk from CNCF. Explore the latency challenges associated with sidecar introduction in service mesh adoption and understand the performance breakdown from kernel to user space. Learn about innovative approaches implemented at Tencent that achieved a 50% latency improvement, including the use of eBPF SOCKMAP and Envoy task scheduler extensions. Gain insights into kernel acceleration techniques, Envoy latency analysis, Istio Mixer telemetry optimization, and future developments in service mesh technology. Discover practical solutions to enhance service mesh performance and overcome adoption barriers in cloud-native environments.
