Key Performance Metrics
Learn about crucial metrics like response time, throughput, and error rates to assess system performance.
Why Metrics Matter
Performance testing isn't just about "making things faster." It's about understanding how your system behaves under load.
Performance metrics are key measurements that help us quantify this behavior. They tell us if our system is meeting user expectations and business goals.
Understanding Response Time
Response Time is the total time it takes for a system to respond to a user request. Think of it as how long you wait after clicking a button until the page loads.
- Average Response Time: The typical time users wait.
- Percentiles (e.g., 90th, 95th): These show the response time for a certain percentage of requests. For example, 95th percentile means 95% of requests were faster than this time. They're great for finding outliers!
