Abstract
A method, system and article of manufacture for estimating the performance of a computer system are provided. Initially, a business pattern representative of the expected usage of the computer system is identified. Then, for each parameter associated with each predefined script, which corresponds to the identified business pattern, a value is established. The computer system hardware characteristics and performance objectives are identified next. The performance estimate is then calculated utilizing the established parameter values, identified hardware characteristics and performance objectives. To calculate the performance estimate, the script measurements data is read from a table of previously measured values, and a weighted average number of page visits per user, a weighted average visit rate and a weighted average service time for each target device in the computer system are calculated. A total response time and a system throughput are calculated by varying each target device queue length and user arrival rate until the performance objectives are reached.
