Core Web Vitals
Max Potential First Input Delay
80 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task.
Cumulative Layout Shift
0.103
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
1.2 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
First Meaningful Paint
1.1 s
First Meaningful Paint measures when the primary content of a page is visible.
Minify CSS
Potential savings of 12 KiB
Minifying CSS files can reduce network payload sizes.
Total Blocking Time
10 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
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.
Serve static assets with an efficient cache policy
20 resources found
A long cache lifetime can speed up repeat visits to your page.
Serve images in next-gen formats
Potential savings of 376 KiB
Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption.
Reduce initial server response time
Root document took 2,290 ms
Keep the server response time for the main document short because all other requests depend on it.
Speed Index
2.4 s
Speed Index shows how quickly the contents of a page are visibly populated.
JavaScript execution time
0.2 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
Time to Interactive
1.3 s
Time to interactive is the amount of time it takes for the page to become fully interactive.
Avoids enormous network payloads
Total size was 1,878 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Avoids an excessive DOM size
645 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Reduce unused JavaScript
Potential savings of 275 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
First Contentful Paint
1.1 s
First Contentful Paint marks the time at which the first text or image is painted.
Reduce unused CSS
Potential savings of 59 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity.
Eliminate render-blocking resources
Potential savings of 940 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.

* These are assets not hosted on the same domain e.g. tracking scripts, iframe embeds, or files hosted on a CDN.
These measurements are for each new visitor, for returning visitors the footprint would be lower based on caching mechanisms.
