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
Largest Contentful Paint
0.8 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
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.
Reduce unused JavaScript
Potential savings of 60 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
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.
Serve static assets with an efficient cache policy
4 resources found
A long cache lifetime can speed up repeat visits to your page.
Speed Index
0.7 s
Speed Index shows how quickly the contents of a page are visibly populated.
Initial server response time was short
Root document took 200 ms
Keep the server response time for the main document short because all other requests depend on it.
Avoids an excessive DOM size
240 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Eliminate render-blocking resources
Potential savings of 260 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.
Avoids enormous network payloads
Total size was 554 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Properly size images
Potential savings of 349 KiB
Serve images that are appropriately-sized to save cellular data and improve load time.
First Contentful Paint
0.5 s
First Contentful Paint marks the time at which the first text or image is painted.
Enable text compression
Potential savings of 57 KiB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes.
Time to Interactive
0.5 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
First Meaningful Paint
0.5 s
First Meaningful Paint measures when the primary content of a page is visible.
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.
