Core Web Vitals

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


0.017

Cumulative Layout Shift measures the movement of visible elements within the viewport.

Largest Contentful Paint


0.6 s

Largest Contentful Paint marks the time at which the largest text or image is painted.

Opportunities

Avoids enormous network payloads


Total size was 183 KiB

Large network payloads cost users real money and are highly correlated with long load times.

Network Round Trip Times


20 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.

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.

First Contentful Paint


0.5 s

First Contentful Paint marks the time at which the first text or image is painted.

Initial server response time was short


Root document took 20 ms

Keep the server response time for the main document short because all other requests depend on it.

First Meaningful Paint


0.6 s

First Meaningful Paint measures when the primary content of a page is visible.

Reduce unused CSS


Potential savings of 14 KiB

Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity.

Server Backend Latencies


120 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.

Time to Interactive


0.6 s

Time to Interactive is the amount of time it takes for the page to become fully interactive.

Avoids an excessive DOM size


447 elements

A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows

Minimizes main-thread work


0.2 s

Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.

Speed Index


0.5 s

Speed Index shows how quickly the contents of a page are visibly populated.

Eliminate render-blocking resources


Potential savings of 60 ms

Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.

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.
