This website has been tested 13 times**
Previous 10 test results are displayed above.
Core Web Vitals
Max Potential First Input Delay
140 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task.
Cumulative Layout Shift
0.005
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
1.6 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 70 ms
Keep the server response time for the main document short because all other requests depend on it.
Avoids enormous network payloads
Total size was 1,922 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Reduce unused CSS
Potential savings of 65 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity.
Total Blocking Time
80 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
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.
Minimizes main-thread work
1.6 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
Defer offscreen images
Potential savings of 139 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive.
First Contentful Paint
0.4 s
First Contentful Paint marks the time at which the first text or image is painted.
Time to Interactive
1.8 s
Time to interactive is the amount of time it takes for the page to become fully interactive.
First Meaningful Paint
0.6 s
First Meaningful Paint measures when the primary content of a page is visible.
Speed Index
1.9 s
Speed Index shows how quickly the contents of a page are visibly populated.
Reduce unused JavaScript
Potential savings of 29 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
Serve images in next-gen formats
Potential savings of 368 KiB
Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption.
Avoids an excessive DOM size
713 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Properly size images
Potential savings of 638 KiB
Serve images that are appropriately-sized to save cellular data and improve load time.
Efficiently encode images
Potential savings of 117 KiB
Optimized images load faster and consume less cellular data.
Serve static assets with an efficient cache policy
88 resources found
A long cache lifetime can speed up repeat visits to your page.
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.
