Core Web Vitals
Max Potential First Input Delay
1,620 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task.
Cumulative Layout Shift
0.005
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
2.8 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Avoids enormous network payloads
Total size was 1,561 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Initial server response time was short
Root document took 240 ms
Keep the server response time for the main document short because all other requests depend on it.
First Meaningful Paint
0.6 s
First Meaningful Paint measures when the primary content of a page is visible.
Minimize main-thread work
9.9 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
Speed Index
6.2 s
Speed Index shows how quickly the contents of a page are visibly populated.
Time to Interactive
6.7 s
Time to interactive is the amount of time it takes for the page to become fully interactive.
Serve static assets with an efficient cache policy
9 resources found
A long cache lifetime can speed up repeat visits to your page.
Reduce unused JavaScript
Potential savings of 378 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
Avoid an excessive DOM size
1,533 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
First Contentful Paint
0.6 s
First Contentful Paint marks the time at which the first text or image is painted.
Total Blocking Time
4,980 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
Defer offscreen images
Potential savings of 25 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive.
Reduce JavaScript execution time
8.5 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
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.
