摘　　要：分析了几种服务器软件体系结构存在的优点与缺陷,设计了一种结合多进程并发与单进程事件驱动优点的对称式多进程事件驱动 SMPED 服务器体系结构。提出了一种新颖的连接调度算法,该算法根据服务器实际吞吐量进行连接分发和资源分配,试图实现服务器吞吐量最大化。仿真试验证明,SMPED 服务器性能在多种网络条件下明显优于现行服务器。Soft architecture of severs have very important effects on their performance. In this paper, we introduce architectures of several prevalent servers and indicate their advantages ＆ shortcomings. A new architecture for high performance server is proposed, which we call the symmetric multi-processes event-driven （SMPED） architecture. SMPED combines advantages of both multi processes concurrent and single process event-driven. In SMPED, a novel schedule algorithm is introduced, which makes use of real throughput of each service process to distribute connection and resource. At last, we evaluate the performance of a Web server based on SMPED. The simulated results show that our SMPED is better than several servers on performance.
