摘　　要：对线程、内存、数据连接等宝贵资源的低效使用已成为B/S体系结构应用软件的主要性能瓶颈。而池技术正是解决这一问题的有效途径。介绍了基于池技术扩展而来的线程池、实例池、连接池的基本原理,阐述了如何将其运用于N层构架体系中相应层,优化整体的系统性能,并对存在的问题提出了改进算法。最后针对现有的池中突发的资源管理调度方法的不足,提出了基于最高效益的调度算法。The main bottleneck of application software, which is based on the B/S architecture, is that the ineffective use of the precious resources such as thread,memory, and data connection. Moreover, the pool technology is an efficient method to conquer this pitfall. First- ly this paper introduces the theory of thread pool, instance pool, connection pool. How to use the pool technology on the corresponding layer of the N layers truss system to optimize the performance of the whole system is also discussed. At last, put forward a new resource scheduling algorithm based on benefit optimization aiming at the shortage of the existing pool resource scheduling algorithm.
