Core Web Vitals
Max Potential First Input Delay
40 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task.
Learn more about the Maximum Potential First Input Delay metric
Cumulative Layout Shift
0
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
2.3 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Initial server response time was short
Root document took 80 ms
Keep the server response time for the main document short because all other requests depend on it.
Serve images in next-gen formats
Potential savings of 144 KiB
Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption.
First Contentful Paint
1.4 s
First Contentful Paint marks the time at which the first text or image is painted.
Reduce unused CSS
Potential savings of 988 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity.
Avoid enormous network payloads
Total size was 2,921 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Minimizes main-thread work
0.6 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
418 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Speed Index
1.4 s
Speed Index shows how quickly the contents of a page are visibly populated.
JavaScript execution time
0.1 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
First Meaningful Paint
1.8 s
First Meaningful Paint measures when the primary content of a page is visible.
Eliminate render-blocking resources
Potential savings of 1,000 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.
Enable text compression
Potential savings of 1,707 KiB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes.
Avoid serving legacy JavaScript to modern browsers
Potential savings of 25 KiB
Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. For your bundled JavaScript, adopt a modern script deployment strategy using module/nomodule feature detection to reduce the amount of code shipped to modern browsers, while retaining support for legacy browsers.
Reduce unused JavaScript
Potential savings of 819 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
Serve static assets with an efficient cache policy
9 resources found
A long cache lifetime can speed up repeat visits to your page.
Time to Interactive
1.8 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
Switch to green hosting
One of the easiest things to do that instantly reduces your impact.
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.
