Capacity Planning_IIS_SP1_TechRef
Applies To: Windows Server 2003 with SP1
The administrators initially wanted to see how their application scaled on a server with four 500-MHz processors running IIS 6.0 in worker process isolation mode. Their goal was to stress the site to see how many requests per second the installation processed at (or close to) 100 percent CPU saturation. By understanding how the application performed when the CPU was saturated, they could begin to understand how the site would scale under a heavy load, and they could begin to plan the capacity of the installation based on traffic estimates. Table 7.11 describes the software and hardware used for this case study.
