Understanding API Latency Testing
The API Speed Tester measures the response time of your HTTP endpoints from your current location. It provides detailed metrics to help you optimize performance.
1
Global Latency Check
We trigger requests from your browser to the target URL, measuring the exact time it takes for the server to accept and respond to the request.
2
Performance Metrics
Analyze Average Latency, P95 (95th percentile), Min, and Max response times to identify occasional spikes or consistent delays.
3
Request Waterfall
Visualize individual request durations to detect patterns of instability or cold starts in your serverless functions.
