Core Web Vitals
Max Potential First Input Delay
20 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task.
Cumulative Layout Shift
0.013
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
0.4 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Minimizes main-thread work
0.2 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
Speed Index
0.6 s
Speed Index shows how quickly the contents of a page are visibly populated.
Reduce unused CSS
Potential savings of 12 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity.
Time to Interactive
0.4 s
Time to interactive is the amount of time it takes for the page to become fully interactive.
Initial server response time was short
Root document took 470 ms
Keep the server response time for the main document short because all other requests depend on it.
Avoids enormous network payloads
Total size was 174 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Eliminate render-blocking resources
Potential savings of 40 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.
First Meaningful Paint
0.4 s
First Meaningful Paint measures when the primary content of a page is visible.
Avoids an excessive DOM size
528 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
JavaScript execution time
0.0 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
First Contentful Paint
0.4 s
First Contentful Paint marks the time at which the first text or image is painted.

* 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.
