Cumulative Layout Shift
0
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
0.7 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
First Meaningful Paint
0.7 s
First Meaningful Paint measures when the primary content of a page is visible.
Speed Index
0.7 s
Speed Index shows how quickly the contents of a page are visibly populated.
Reduce unused JavaScript
Potential savings of 117 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
Avoids enormous network payloads
Total size was 535 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Avoids an excessive DOM size
348 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Total Blocking Time
10 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
Reduce unused CSS
Potential savings of 13 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity.
Eliminate render-blocking resources
Potential savings of 400 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.
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.
Properly size images
Potential savings of 67 KiB
Serve images that are appropriately-sized to save cellular data and improve load time.
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.
Serve static assets with an efficient cache policy
19 resources found
A long cache lifetime can speed up repeat visits to your page.
Time to Interactive
1.2 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
First Contentful Paint
0.7 s
First Contentful Paint marks the time at which the first text or image is painted.
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.
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.
