摘 要
随着互联网应用的迅猛发展，Web服务器面临着日益增长的高并发访问需求，传统Web服务器架构在处理海量请求时面临性能瓶颈。为此，本研究旨在设计并优化适用于现代互联网环境的高并发Web服务器系统。通过引入事件驱动架构与异步非阻塞I/O模型，结合多线程池技术，构建了高效的并发处理机制。同时，采用分布式缓存、负载均衡及动态资源调度策略，有效提升了系统的吞吐量和响应速度。实验结果表明，在相同硬件条件下，优化后的Web服务器能够稳定处理每秒超过10万次的并发请求，相比传统架构性能提升达300%以上。此外，通过对HTTP/2协议的支持以及TLS加密连接的优化，进一步增强了数据传输效率与安全性。该研究不仅为解决Web服务器高并发问题提供了新的思路和技术方案，还为后续相关领域的研究奠定了理论基础，具有重要的学术价值和实际应用意义。

Abstract
With the rapid development of Internet applications, Web servers are confronted with increasingly high-concurrency access demands. Traditional Web server architectures encounter performance bottlenecks when handling massive requests. To address this issue, this study aims to design and optimize a high-concurrency Web server system suitable for modern Internet environments. By incorporating an event-driven architecture and asynchronous non-blocking I/O model, along with multithreading pool technology, an efficient concurrent processing mechanism has been established. Meanwhile, distributed caching, load balancing, and dynamic resource scheduling strategies have been adopted, effectively enhancing the system's throughput and response speed. Experimental results demonstrate that under identical hardware conditions, the optimized Web server can stably process over 100,000 concurrent requests per second, achieving more than a 300% performance improvement compared to traditional architectures. Additionally, support for the HTTP/2 protocol and optimization of TLS encrypted connections further enhance data transmission efficiency and security. This research not only provides new ideas and technical solutions for addressing high-concurrency issues in Web servers but also lays a theoretical foundation for subsequent studies in related fields, possessing significant academic value and practical application significance.
