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
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.
Avoids an excessive DOM size
501 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
First Contentful Paint
0.3 s
First Contentful Paint marks the time at which the first text or image is painted.
Speed Index
0.3 s
Speed Index shows how quickly the contents of a page are visibly populated.
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 Meaningful Paint
0.3 s
First Meaningful Paint measures when the primary content of a page is visible.
Properly size images
Potential savings of 377 KiB
Serve images that are appropriately-sized to save cellular data and improve load time.
Initial server response time was short
Root document took 120 ms
Keep the server response time for the main document short because all other requests depend on it.
Time to Interactive
0.3 s
Time to interactive is the amount of time it takes for the page to become fully interactive.
Serve images in next-gen formats
Potential savings of 158 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 607 KiB
Large network payloads cost users real money and are highly correlated with long load times.
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.
