Performance prediction

Definition

Performance prediction is the process of estimating how a system will behave under specific conditions, focusing on metrics like speed, efficiency, and resource usage. It involves using models to simulate potential outcomes and assess whether the system meets desired performance criteria. This is particularly relevant in designing complex systems where understanding interactions and dependencies can significantly impact performance outcomes.
