Page Performance Metrics

Note: Metric availability will vary

Please note: Availability of metrics will vary based on the browser being tested. Also, the way a site performs in some conditions may not predict how well it will perform in others, so we encourage testing in a variety of browsers, devices, & locations.

First Contentful Paint (FCP)

3.93S (poor)

At 75th percentile of visits.

Field metric only, no WPT test run data.

Largest Contentful Paint (LCP)

4.11S (poor)

At 75th percentile of visits.

Field metric only, no WPT test run data.

Cumulative Layout Shift (CLS)

0.79 (poor)

At 75th percentile of visits.

0.79 worse than this WPT test run's first view (0). Why?

Time to First Byte (TTFB)

1.12S (fair)

At 75th percentile of visits.

.14S worse than this WPT test run's first view (.98S). Why?

Interaction to Next Paint (INP)

.17S (good)

At 75th percentile of visits.

Field metric only, no WPT test run data.

Note: Why can real browser usage metrics vary from test run metrics?

Variance between your test run and real world usage is expected because a WebPageTest run uses a specific connection speed, and real world data spans all connection speeds. To closely match the p75 user in WebPageTest, try rerunning your test using a different connection speed.
