Max Potential First Input Delay
20 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
Cumulative Layout Shift
0
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
1.0 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Eliminate render-blocking resources
Potential savings of 270 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.
Avoids an excessive DOM size
458 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
First Contentful Paint
0.8 s
First Contentful Paint marks the time at which the first text or image is painted.
Avoids enormous network payloads
Total size was 1,180 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Speed Index
1.1 s
Speed Index shows how quickly the contents of a page are visibly populated.
Reduce initial server response time
Root document took 890 ms
Keep the server response time for the main document short because all other requests depend on it.
First Meaningful Paint
0.8 s
First Meaningful Paint measures when the primary content of a page is visible.
Reduce unused CSS
Potential savings of 216 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity.
Properly size images
Potential savings of 104 KiB
Serve images that are appropriately-sized to save cellular data and improve load time.
Reduce unused JavaScript
Potential savings of 168 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
Serve static assets with an efficient cache policy
41 resources found
A long cache lifetime can speed up repeat visits to your page.
Time to Interactive
0.8 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
Minimizes main-thread work
0.4 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
Enable text compression
Potential savings of 520 KiB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes.
JavaScript execution time
0.1 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
Notes
* 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.
