GET REAL! THE IMPORTANCE OF REALISM FOR WEB SITE CAPACITY ASSESSMENT

摘要

Web system capacity assessment often carefully emulates user behavior. User behavior dramatically affects system performance, but comprises only half the story. Network realism plays a major role in system performance, and must be considered for a reliable reflection of performance in the real world. Network realism includes packet loss, link latencies, millions of IP addresses, and protocols. The paper will show the benefits gained from capacity assessment, discuss the impact of both user and network behavior, explain how they affect performance, and present results of a realism study.
