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.
Largest Contentful Paint
0.3 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Avoids an excessive DOM size
640 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Properly size images
Potential savings of 20 KiB
Serve images that are appropriately-sized to save cellular data and improve load time.
Speed Index
0.7 s
Speed Index shows how quickly the contents of a page are visibly populated.
Minimizes main-thread work
0.1 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
First Contentful Paint
0.3 s
First Contentful Paint marks the time at which the first text or image is painted.
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.
Serve images in next-gen formats
Potential savings of 24 KiB
Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption.
Avoids enormous network payloads
Total size was 85 KiB
Large network payloads cost users real money and are highly correlated with long load times.
First Meaningful Paint
0.3 s
First Meaningful Paint measures when the primary content of a page is visible.
Uses efficient cache policy on static assets
3 resources found
A long cache lifetime can speed up repeat visits to your page.
Time to Interactive
0.3 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 60 ms
Keep the server response time for the main document short because all other requests depend on it.
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.
