What are examples of performance metrics?

Performance metrics are specific measurements used to evaluate how well a system performs. The choice that includes response time and capacity directly relates to assessing the efficiency and effectiveness of a system.

Response time is a crucial metric, evaluating how quickly a system can process a request or perform a task. A shorter response time indicates that a system is performing efficiently, which is critical for user satisfaction, especially in real-time applications like web services or online games.

Capacity refers to the maximum amount of work or the number of users a system can handle before performance starts to degrade. Knowing the capacity helps in planning for scalability and ensures that the system can meet user demands without significant delays or outages.

The other options highlight different aspects of software and system design but do not specifically address measurable performance aspects to the same extent. Compatibility and portability are related to how well software can work across different environments, while user interface design focuses on usability rather than performance metrics. Code efficiency, while important for performance, is a more specific aspect of programming rather than a direct performance metric itself. Therefore, response time and capacity provide concrete, measurable values that can be directly used to evaluate the performance of a system.
