Frequently Asked Questions
What is load testing?
Load testing is the process of simulating multiple concurrent users accessing a website or API simultaneously. It helps you understand how your application performs under stress, identify bottlenecks, and determine the maximum capacity before degradation occurs.
How many virtual users can I simulate?
You can simulate between 1 and 200 virtual users concurrently. Each virtual user sends requests with a realistic think-time (0.5–2 seconds between requests) to simulate real human behavior.
What metrics are collected?
We collect total requests, success/error rates, average latency, P50/P95/P99 latency percentiles, min/max response time, requests per second (RPS), and HTTP status code distribution. All metrics are available in real-time and in the downloadable report.
What does the verdict mean?
Stable (✅) means the application handled the load well with low error rates and fast response times. Degrading (⚠️) means some performance issues were detected. Failing (❌) indicates significant problems under load, such as high error rates or extreme latency.
Is this tool safe to use?
Yes. We enforce strict limits: maximum 200 users, 2-minute duration, 3 tests per minute per user, and only 3 concurrent tests globally. Private/internal IP addresses are blocked. Each request includes an identifying User-Agent header. This tool is designed for performance testing, not abuse.
What is P95 latency?
P95 (95th percentile) latency means that 95% of all requests completed within that time. It's a better indicator of user experience than average latency because it captures the slower requests that affect real users.
