Load testing requires domain ownership verification.
Sign in, then register and verify your domain in the “Domains” tab in the sidebar.
⚠️ When Cloudflare Proxy is enabled, load test results may appear abnormally slow.
For accurate testing, set your domain’s DNS record to “DNS only” (grey cloud icon).

What is a K6 Load Test?
K6 is a modern load testing tool by Grafana. You write test scenarios in JavaScript to validate the performance and stability of websites and APIs.
🔧 Key concepts:
• Virtual Users (VUs): number of concurrent virtual users
• Duration: how long the test runs
• Think Time: wait time between requests (simulates real user behavior)
• P95 response time: time under which 95% of requests complete
📊 Why P95 matters:
Averages can be skewed by a few very fast requests. P95 reflects what most users (95%) actually experience, so it’s more realistic.
🎯 Role of Think Time:
Real users pause to read or decide the next action. Think time produces more realistic load patterns.

📋 Certificate issuance requirements:
• At least 30 VUs + 30 s
• Achieve grade B or higher
• Sign‑in and domain ownership verification required
🔐 How to verify domain ownership:
1) Register your domain in the “Domains” tab in the sidebar
2) Verify via TXT record or file upload
3) Run the load test once verification is complete
