Application Performance Metrics

Performance is a key usability and quality metric. Phrases like making fast and improving scalability are vague and subjective and don't make very good performance targets. As a result, the industry has come up with widely accepted terms for quantifying performance:

• Latency (Response time) - amount of time in ms, required to complete a unit of work
• Elapsed time - measures time taken for a batch of operations to complete
• Throughput - amount of work an application can accomplish per unit of time (seconds)
