Performance Metrics

Every action timed to the millisecond. See exactly where slowdowns occur with a full step-by-step timeline.

What gets measured

LazyHippo records wall-clock timing for every step: page loads, form fills, button clicks, redirects, email waits, and API responses. The report shows a full timeline so you can spot exactly where slowdowns occur.

For pressure tests, you get aggregate metrics across all concurrent sessions: p50, p95, p99 latencies, error rates, and throughput over time.
