This website has been tested 11 times**
Previous 10 test results are displayed above.
Core Web Vitals
Max Potential First Input Delay
120 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task.
Cumulative Layout Shift
0.92
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
1.1 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
JavaScript execution time
0.5 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
First Meaningful Paint
0.9 s
First Meaningful Paint measures when the primary content of a page is visible.
Avoid an excessive DOM size
999 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
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.
Minimizes main-thread work
1.4 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
First Contentful Paint
0.7 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 130 ms
Keep the server response time for the main document short because all other requests depend on it.
Uses efficient cache policy on static assets
4 resources found
A long cache lifetime can speed up repeat visits to your page.
Reduce unused JavaScript
Potential savings of 61 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
Properly size images
Potential savings of 336 KiB
Serve images that are appropriately-sized to save cellular data and improve load time.
Total Blocking Time
100 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
Avoids enormous network payloads
Total size was 1,418 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Speed Index
0.8 s
Speed Index shows how quickly the contents of a page are visibly populated.
Time to Interactive
1.2 s
Time to interactive is the amount of time it takes for the page to become fully interactive.
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.
