| Since the 90th of the 20 century, by right of its low demand for hardware, short development cycle, well expansibility and maintainability, the B/S model based Web system becomes mainstream structure of the current enterprise information system gradually.The Web system becomes very popular, at the same time, it emerges some problems that can not be ignored. Such as the response time of a respectable amount of system can not satisfy the demand of user; Also the response time of some systems will increase suddenly, even cause denial of service when extended subsequent accesses occur.Currently, the J2EE based Web system is on the leading status in the enterprise solutions. There are various impacts for performance of the J2EE based Web system, such as hardware (the computer and network), operating system, Java virtual machine, database management system, database instance, J2EE server and J2EE application etc.This paper will associate the process model of Web system performance tuning and the computer assistant solution of Web system performance tuning, and aim at code performance tuning of the J2EE framework based Web system, mainly expatiate the design and implementation of Web system performance tuning supporting system (WPT). |
