| English Abstract | 现有的Web容器多采用线程池体系结构，而Web容器所支撑的动态Web组件在执行过程中可能需要获取多种共享资源，由共享资源并发量限制导致的线程阻塞 可能会严重影响性能。提出了一种资源敏感的Web容器体系结构ROSA(resource-oriented staged architecture)。当某些共享资源达到饱和时，若Web容器接到对需要这些资源的Web组件的请求，ROSA会暂缓为这些请求提供服务以减少线 程阻塞。基于排队Petri网，建立了ROSA结构和线程池结构的性能模型，通过模型仿真和负载实验验证了ROSA体系结构的性能优势。 |

| Abstract | Most of the current Web containers adopt thread-pool architecture. A Web component which Web con-tainer supports may obtain multiple shared resources during runtime. The concurrency limits of these resources may cause thread-blocking and seriously hinder the performance. This paper proposes a resource-oriented Web container architecture,which is named ROSA(resource-oriented staged architecture) . When some shared resources are satu-rated and Web container receives the requests for Web components demanding these resources,ROSA will post-pone serving these requests in order to reduce thread-blocking. The paper builds the performance model of ROSA and thread-pool architecture using queuing Petri nets,and the experimental results of simulation and load testing show the performance advantage of ROSA. |
