Performance Modeling

Performance modeling is a structured and repeatable approach to modeling the performance of your software. It's both an information structure and a process to help you capture performance-related information, including performance threats. When you create performance models, you identify application scenarios and your performance objectives. Your performance objectives are your measurable criteria, such as response time, throughput (how much work in how much time), and resource utilization (CPU, memory, disk I/O, and network I/O). You break down your performance scenarios into steps and assign performance budgets. Your budget defines the resources and constraints across your performance objectives. You can use performance modeling to shape your application's design to meet your performance objectives, and reduce risk.
