THE PERFORMANCE EVALUATION OF LARGE SCALE WEB SERVERS

The rapidly increased amount of Web users makes single node Web server out of date and the traditional multi node systems have the defects of difficult maintenance and imbalance traffic. The systems with single entry point, which is made up of cluster system and scalable software, can meet these needs. The multi node Web server and email server are introduced, which are implemented in Dawning 2000 II. Their performance abilities are evaluated. SpecWeb99 is used as evaluating tools for the performance of Web server, the email performance evaluating system is constructed by NCIC （national center for intelligent computing systems） and their results show the excellent scalability of this architecture.
