Core Web Vitals
Max Potential First Input Delay
70 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
0.007
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
1.1 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Time to Interactive
1.6 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
Avoid an excessive DOM size
1,063 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Speed Index
2.9 s
Speed Index shows how quickly the contents of a page are visibly populated.
Avoids enormous network payloads
Total size was 1,690 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Reduce unused JavaScript
Est savings of 226 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
Reduce unused CSS
Est savings of 140 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity.
First Contentful Paint
0.6 s
First Contentful Paint marks the time at which the first text or image is painted.
JavaScript execution time
0.3 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
Server Backend Latencies
0 ms
Server latencies can impact web performance. If the server latency of an origin is high, it's an indication the server is overloaded or has poor backend performance.
Eliminate render-blocking resources
Est savings of 220 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.
Network Round Trip Times
10 ms
Network round trip times (RTT) have a large impact on performance. If the RTT to an origin is high, it's an indication that servers closer to the user could improve performance.
Reduce initial server response time
Root document took 1,470 ms
Keep the server response time for the main document short because all other requests depend on it.
Total Blocking Time
20 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
Minimizes main-thread work
1.1 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.
** 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.
