Core Web Vitals

Max Potential First Input Delay


500 ms

The maximum potential First Input Delay that your users could experience is the duration of the longest task.

Largest Contentful Paint


0.6 s

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

Opportunities

Network Round Trip Times


0 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.

Avoids enormous network payloads


Total size was 456 KiB

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

Serve static assets with an efficient cache policy


1 resource found

A long cache lifetime can speed up repeat visits to your page.

First Contentful Paint


0.3 s

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

JavaScript execution time


0.7 s

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

Minimizes main-thread work


1.6 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 65 KiB

Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.

Time to Interactive


1.2 s

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

Total Blocking Time


540 ms

Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.

Avoid an excessive DOM size


1,463 elements

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

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.

Speed Index


1.9 s

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

First Meaningful Paint


0.3 s

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

Reduce initial server response time


Root document took 680 ms

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

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.
