Core Web Vitals
Max Potential First Input Delay
90 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task.
Cumulative Layout Shift
0.009
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
1.9 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Avoid multiple page redirects
Potential savings of 230 ms
Redirects introduce additional delays before the page can be loaded.
Serve static assets with an efficient cache policy
10 resources found
A long cache lifetime can speed up repeat visits to your page.
Total Blocking Time
20 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
First Contentful Paint
1.2 s
First Contentful Paint marks the time at which the first text or image is painted.
Reduce unused CSS
Potential savings of 256 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity.
Minimizes main-thread work
0.5 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
Avoids enormous network payloads
Total size was 1,023 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Reduce unused JavaScript
Potential savings of 215 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
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
1.9 s
Time to interactive is the amount of time it takes for the page to become fully interactive.
Enable text compression
Potential savings of 416 KiB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes.
Eliminate render-blocking resources
Potential savings of 250 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.
Speed Index
1.3 s
Speed Index shows how quickly the contents of a page are visibly populated.
Initial server response time was short
Root document took 130 ms
Keep the server response time for the main document short because all other requests depend on it.
First Meaningful Paint
1.3 s
First Meaningful Paint measures when the primary content of a page is visible.
Avoids an excessive DOM size
305 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
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.
