Core Web Vitals
Max Potential First Input Delay
260 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task.

Cumulative Layout Shift
0.077
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
0.8 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Serve static assets with an efficient cache policy
53 resources found
A long cache lifetime can speed up repeat visits to your page.
Reduce unused CSS
Potential savings of 64 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity.
Minimize main-thread work
2.7 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
Eliminate render-blocking resources
Potential savings of 190 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.
First Contentful Paint
0.8 s
First Contentful Paint marks the time at which the first text or image is painted.
Total Blocking Time
270 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
Serve images in next-gen formats
Potential savings of 272 KiB
Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption.
Time to Interactive
5.8 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
Avoids an excessive DOM size
680 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Reduce JavaScript execution time
1.9 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
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.
Avoid enormous network payloads
Total size was 5,517 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Reduce unused JavaScript
Potential savings of 1,857 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
Minify JavaScript
Potential savings of 12 KiB
Minifying JavaScript files can reduce payload sizes and script parse time.
Defer offscreen images
Potential savings of 593 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive.
First Meaningful Paint
0.8 s
First Meaningful Paint measures when the primary content of a page is visible.
Speed Index
2.3 s
Speed Index shows how quickly the contents of a page are visibly populated.
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.
