Some of these applications have very strict real-time requirements, which requires us to improve their performance to achieve faster service speeds. To achieve faster service speeds, a scenario is that when two applications that call each other are deployed on the same node, each request and response must pass through the socket layer, TCP/IP protocol stack, data link layer, and physical layer. If requests and responses bypass the TCP/IP protocol stack and directly redirect data packets to the peer socket at the socket layer, it will greatly reduce the time consumed for sending data packets and increase the speed of the service. Based on this idea, eBPF technology maps and stores socket information, and uses helper functions to achieve the ability to redirect data packets to the peer socket layer. Cilium is based on this ability of eBPF to achieve socket acceleration effects. - [20230428 | Kubernetes 1.27: Speed Up Pod Startup](./230428-pod-startup.md) How to speed up Pod startup on nodes in a large cluster?
