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
0.173
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
1.5 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
JavaScript execution time
0.5 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
Serve static assets with an efficient cache policy
93 resources found
A long cache lifetime can speed up repeat visits to your page.
Avoids enormous network payloads
Total size was 1,928 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Avoids an excessive DOM size
374 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Minimizes main-thread work
1.2 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
Time to Interactive
1.8 s
Time to interactive is the amount of time it takes for the page to become fully interactive.
Total Blocking Time
50 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
Reduce initial server response time
Root document took 1,600 ms
Keep the server response time for the main document short because all other requests depend on it.
First Contentful Paint
0.7 s
First Contentful Paint marks the time at which the first text or image is painted.
First Meaningful Paint
0.7 s
First Meaningful Paint measures when the primary content of a page is visible.
Remove duplicate modules in JavaScript bundles
Potential savings of 17 KiB
Remove large, duplicate JavaScript modules from bundles to reduce unnecessary bytes consumed by network activity.
Speed Index
1.9 s
Speed Index shows how quickly the contents of a page are visibly populated.
Reduce unused JavaScript
Potential savings of 48 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
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.
