基于池技术的高效N层Web应用体系研究

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。

Research for High Efficient N Layers Web Application System Based on Pool Technology

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.Firstly 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.
