Web服务器在分布式系统中主要担当接入的角色,它的接入性能、容量和响应速度是衡量系统性能的主要技术指标。我们的系统是基于Web服务器技术的银行金融设备的监控和管理。Web服务器接收数据和发送响应,数据采集量比较大,而且管理设备多,会话数目也较多,系统负荷比较大。在系统建设中,主要从以下几个方面考虑提升Web服务器性能:(1)数据交换协议的选定;(2)基于组件技术的系统构成;(3)基于J2EE平台技术构造Web服务器系统;(4)优化后台数据库的连接性能,提高获取信息;(5)优化Web服务器软件系统,提高系统的网络带宽。Web服务器性能的改善不仅是Web服务器本身的问题,而是一个整体系统性能优化的问题。只有从全局角度考虑这个问题,才能根本提升Web服务器性能。
Web server mainly plays the role of access in distributed system. Its access performance, capacity and response speed are the main technical indicators to measure system performance. Our system is based on Web server technology, banking financial equipment monitoring and management. Web server to receive data and send responses, data collection is relatively large, and the management of equipment, the number of sessions are also more system load. In the system construction, we mainly consider the following aspects to improve the performance of Web server: (1) the selection of data exchange protocol; (2) the system structure based on component technology; (3) the construction of Web server system based on J2EE platform technology; 4) optimize the background database connection performance, improve access to information; (5) optimize the Web server software system to improve the system’s network bandwidth. Web server performance improvement is not only the Web server itself, but an overall system performance optimization problem. Only consider this issue from a global perspective, in order to fundamentally improve Web server performance.
