Linux下的网络编程框架与性能优化
摘 要
随着互联网技术的迅猛发展，网络编程在Linux系统下的应用日益广泛，对高效稳定的网络编程框架及性能优化的需求愈发迫切。本研究聚焦于Linux环境下的网络编程框架与性能优化，旨在构建一个高效、稳定且易于扩展的网络编程模型，以满足现代网络应用对高性能和低延迟的要求。通过对现有网络编程框架的深入分析，结合Linux内核特性，提出了一种基于事件驱动与异步I/O机制相结合的新型网络编程框架。该框架利用epoll机制实现高效的事件监听，并通过多线程池技术提高并发处理能力。实验结果表明，在相同硬件条件下，所提出的框架相比传统同步阻塞模式可将吞吐量提升30%以上，响应时间缩短25%，特别是在高并发场景下优势明显。此外，针对内存管理进行了优化，采用零拷贝技术和内存池策略有效降低了系统开销。

Abstract
With the rapid development of Internet technology, the application of network programming in Linux system is increasingly extensive, and the need for efficient and stable network programming fr amework and performance optimization is more urgent. This study focuses on the network programming fr amework and performance optimization in the Linux environment, aiming to build an efficient, stable and easily scalable network programming model to meet the requirements of high performance and low latency for modern network applications. Through thorough analysis of existing network programming fr amework combined with Linux kernel features, a novel network programming fr amework based on the combination of event-driven and asynchronous I / O mechanism is proposed. The fr amework enables efficient event listening using epl mechanism and improves concurrent processing through multi-threaded pooling technology. The experimental results show that under the same hardware conditions, the proposed fr amework can improve the throughput by more than 30% and shorten the response time by 25% compared with the traditional synchronous blocking mode, especially in the high concurrency scenario. In addition, the memory management is optimized, using zero copy technology and memory pooling strategy to effectively reduce the system overhead.
