Identify slow URLs, inspect page-load phases, and drill into per-URL network calls during a hybrid load test.

The Browser tab highlights the most important frontend performance signals for your application during load. Use this page to identify slow URLs, compare key metrics across the site, and drill into the network calls that explain a slow page.

Worst-performing URLs

The Worst-performing URLs chart surfaces the top 5 URLs with the worst values for the selected metric. Use the toggle to switch between LCP, INP, CLS, FCP, and TTFB. Values represent the percentile selected in the report header (for example, p75) across all virtual users.

Use this view to decide which URLs to prioritize for optimization.

Detailed URL table

The Detailed URL table lists every tested URL with its Web Vitals values and a breakdown of page-load phases (for example, DNS, connect, request, response, render). Sort by any column or search by URL to narrow the list. A dash (-) in a cell means the metric was not captured for that URL.

URL drill-in: per-URL network calls

Select any row in the detailed URL table to open the per-URL drill-in view. This view lists every network call made while loading that URL along with each call’s response code and individual response-time performance, so you can pinpoint which API or asset is responsible for a slow page.

URL Performance breakdown

This view displays a comprehensive breakdown of your URL’s performance, including page-load phase distribution, individual network call performance, and response-code metrics. Use this data to understand where bottlenecks occur and identify optimization opportunities.
