Core Web Vitals
Max Potential First Input Delay
110 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task.
Largest Contentful Paint
1.3 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Avoids enormous network payloads
Total size was 2,279 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Properly size images
Potential savings of 396 KiB
Serve images that are appropriately-sized to save cellular data and improve load time.
Serve images in next-gen formats
Potential savings of 507 KiB
Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption.
Reduce unused JavaScript
Potential savings of 116 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
First Meaningful Paint
0.8 s
First Meaningful Paint measures when the primary content of a page is visible.
Defer offscreen images
Potential savings of 635 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive.
Time to Interactive
1.3 s
Time to interactive is the amount of time it takes for the page to become fully interactive.
Minimizes main-thread work
0.9 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
Speed Index
0.8 s
Speed Index shows how quickly the contents of a page are visibly populated.
Avoid an excessive DOM size
1,844 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
First Contentful Paint
0.4 s
First Contentful Paint marks the time at which the first text or image is painted.
Initial server response time was short
Root document took 190 ms
Keep the server response time for the main document short because all other requests depend on it.
JavaScript execution time
0.3 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
13 resources found
A long cache lifetime can speed up repeat visits to your page.
Total Blocking Time
50 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
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.
