Abstract

A WebGIS system based on Java Servlet mode is designed and implemented with GeoServer and OpenLayers. WebGIS server side performances are studied and a variety of solutions put forward for performance optimization, including JVM (Java Virtual Machine) performance tuning, the establishment and improvement of cache server, and using tmpfs (a memory-based file system) to save cache pictures, etc. A series of experiments are also designed to analyse and compare the results. Studies show that these solutions can effectively improve server performance, and are economic, simple, convenient, and highly practical.
