Core Web Vitals

Max Potential First Input Delay


90 ms

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

Cumulative Layout Shift


0.483

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

Largest Contentful Paint


4.5 s

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

Opportunities

Reduce unused CSS


Potential savings of 1,170 KiB

Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity.

Speed Index


2.8 s

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

Reduce initial server response time


Root document took 1,500 ms

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

Minimizes main-thread work


1.5 s

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

First Meaningful Paint


0.6 s

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

Total Blocking Time


90 ms

Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.

Time to Interactive


4.7 s

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

Avoid enormous network payloads


Total size was 4,032 KiB

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

Enable text compression


Potential savings of 2,071 KiB

Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes.

JavaScript execution time


0.6 s

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

Avoid an excessive DOM size


1,110 elements

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

Uses efficient cache policy on static assets


1 resource found

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

Eliminate render-blocking resources


Potential savings of 150 ms

Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.

Reduce unused JavaScript


Potential savings of 932 KiB

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

First Contentful Paint


0.6 s

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

Notes

* These are assets not hosted on the same domain e.g. tracking scripts, iframe embeds, or files hosted on a CDN.

** This was only counted from 11.Apr.2021.

These measurements are for each new visitor, for returning visitors the footprint would be lower based on caching mechanisms.
