(Collected anonymously by Chrome browser from August 8, 2024 to September 4, 2024 | Full Report)

First Contentful Paint (FCP)

1.03S (good)

At 75th percentile of visits.

.02S better than this WPT test run's first view (1.05S). Why?

Largest Contentful Paint (LCP)

1.54S (good)

At 75th percentile of visits.

.60S better than this WPT test run's first view (2.14S). Why?

Cumulative Layout Shift (CLS)

0.19 (fair)

At 75th percentile of visits.

0.189 worse than this WPT test run's first view (0.001). Why?

Time to First Byte (TTFB)

.72S (good)

At 75th percentile of visits.

.42S worse than this WPT test run's first view (.30S). Why?

Interaction to Next Paint (INP)

.06S (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.
