Performance engineering for software architectures

Software Performance Engineering (SPE) is a method for constructing software systems that meet performance goals. SPE includes techniques for gathering data, coping with uncertainty, constructing and evaluating performance models, evaluating alternatives, and verifying models and validating results. It also includes strategies for the effective use of these techniques. This presentation addresses the architectural stage performance evaluation the SPE process continues throughout development at more detailed levels to manage the performance of the evolving system
