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.

Cumulative Layout Shift
0.001
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
1.3 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Avoids an excessive DOM size
295 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
First Meaningful Paint
0.7 s
First Meaningful Paint measures when the primary content of a page is visible.
Time to Interactive
0.7 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
Eliminate render-blocking resources
Potential savings of 470 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.
Enable text compression
Potential savings of 122 KiB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes.
Avoids enormous network payloads
Total size was 394 KiB
Large network payloads cost users real money and are highly correlated with long load times.
JavaScript execution time
0.0 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
Speed Index
0.7 s
Speed Index shows how quickly the contents of a page are visibly populated.
Preload Largest Contentful Paint image
Potential savings of 30 ms
If the LCP element is dynamically added to the page, you should preload the image in order to improve LCP.
Minimizes main-thread work
0.1 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
Initial server response time was short
Root document took 240 ms
Keep the server response time for the main document short because all other requests depend on it.
Properly size images
Potential savings of 48 KiB
Serve images that are appropriately-sized to save cellular data and improve load time.
Serve static assets with an efficient cache policy
4 resources found
A long cache lifetime can speed up repeat visits to your page.
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.
These measurements are for each new visitor, for returning visitors the footprint would be lower based on caching mechanisms.
