Core Web Vitals

Max Potential First Input Delay


40 ms

The maximum potential First Input Delay that your users could experience is the duration of the longest task.

Cumulative Layout Shift


0

Cumulative Layout Shift measures the movement of visible elements within the viewport.

Largest Contentful Paint


0.5 s

Largest Contentful Paint marks the time at which the largest text or image is painted.

Opportunities

Avoids an excessive DOM size


233 elements

A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows

Speed Index


0.3 s

Speed Index shows how quickly the contents of a page are visibly populated.

Uses efficient cache policy on static assets


2 resources found

A long cache lifetime can speed up repeat visits to your page.

Time to Interactive


0.5 s

Time to interactive is the amount of time it takes for the page to become fully interactive.

First Meaningful Paint


0.5 s

First Meaningful Paint measures when the primary content of a page is visible.

Initial server response time was short


Root document took 70 ms

Keep the server response time for the main document short because all other requests depend on it.

JavaScript execution time


0.1 s

Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.

Reduce unused JavaScript


Potential savings of 56 KiB

Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.

First Contentful Paint


0.3 s

First Contentful Paint marks the time at which the first text or image is painted.

Minimizes main-thread work


0.3 s

Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.

Avoids enormous network payloads


Total size was 233 KiB

Large network payloads cost users real money and are highly correlated with long load times.
