Max Potential First Input Delay
250 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task.
Learn more about the Maximum Potential First Input Delay metric
Largest Contentful Paint
2.9 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Avoids an excessive DOM size
208 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Reduce JavaScript execution time
1.7 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
Serve images in next-gen formats
Potential savings of 178 KiB
Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption.
Defer offscreen images
Potential savings of 299 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive.
Speed Index
1.6 s
Speed Index shows how quickly the contents of a page are visibly populated.
Total Blocking Time
410 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
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.
Reduce unused JavaScript
Potential savings of 675 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
Eliminate render-blocking resources
Potential savings of 80 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.
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.
Reduce unused CSS
Potential savings of 68 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity.
Efficiently encode images
Potential savings of 50 KiB
Optimized images load faster and consume less cellular data.
Time to Interactive
2.9 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
First Meaningful Paint
0.7 s
First Meaningful Paint measures when the primary content of a page is visible.
Serve static assets with an efficient cache policy
4 resources found
A long cache lifetime can speed up repeat visits to your page.
Avoids enormous network payloads
Total size was 1,953 KiB
Large network payloads cost users real money and are highly correlated with long load times.
First Contentful Paint
0.7 s
First Contentful Paint marks the time at which the first text or image is painted.
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.
