摘 要
随着云计算技术的快速发展，云原生架构已成为构建现代化分布式系统的核心范式，而服务网格作为云原生生态系统中的关键技术组件，为微服务间的通信提供了透明、可观察和可控的基础设施支持。然而，服务网格在提升系统可观测性和治理能力的同时，也引入了额外的性能开销和复杂性瓶颈。本研究旨在深入探讨服务网格的技术原理，并对其性能瓶颈进行全面分析。通过结合理论建模与实验验证的方法，本文首先剖析了服务网格的核心机制，包括数据平面与控制平面的交互模式、流量管理策略以及安全特性实现方式。基于实际部署场景，对主流服务网格框架（如Istio、Linkerd）进行了性能测试与对比分析，重点关注延迟、吞吐量及资源消耗等关键指标。服务网格的性能开销主要来源于代理层的数据处理与控制平面的配置分发，且其影响程度与网络规模、请求负载和服务拓扑密切相关。

Abstract
With the rapid development of cloud computing technology, cloud native architecture has become the core paradigm for building modern distributed systems, and service grid, as a key technology component in the cloud native ecosystem, provides transparent, observable and controllable infrastructure support for communication between microservices. However, while service grids improve system observability and governance, they also introduce additional performance overhead and complexity bottlenecks. The purpose of this study is to deeply discuss the technical principle of service grid and comprehensively analyze its performance bottleneck. By combining theoretical modeling and experimental verification, this paper first analyzes the core mechanism of service grid, including the interaction mode of data plane and control plane, traffic management strategy and security feature implementation. Based on actual deployment scenarios, this paper tests and compares the performance of mainstream service grid fr ameworks (such as Istio and Linkerd), focusing on key indicators such as latency, throughput, and resource consumption. The performance cost of the service grid mainly comes from the data processing of the agent layer and the configuration and distribution of the control plane, and its impact is closely related to the network scale, request load and service topology.
