摘要: 提出了一种基于全局内存对象缓冲池的高性能分布式Web Proxy模型,通过在系统范围内构建类似于分布式共享存储器系统的缓冲池,并将分布式Web Proxy系统中访问最频繁的Web对象置于其中,则Web对象的平均服务时间缩短,提高了系统性能。通过实际Proxy服务器的访问日志进行了系统性能仿真,结果表明,该机制可以提高分布式Web Proxy服务器的性能。

Abstract: his paper proposes a high performance distributed Web proxy model based on global in-memory object caching pool (GMOCP). It introduces a DSM like in-memory caching pool in system wide, and caching hottest objects in GMOCP, the average service time on these objects can be reduced, and system performance is improved. Based on trace-driven simulation method,the system is evaluated. The results show good speedup on performance of distributed proxy servers.
