This website has been tested 20 times**

Previous 10 test results are displayed above.

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.

Largest Contentful Paint


0.5 s

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

Opportunities

Initial server response time was short


Root document took 10 ms

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

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.

Server Backend Latencies


30 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.

First Meaningful Paint


0.3 s

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

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.

Eliminate render-blocking resources


Potential savings of 20 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 24 KiB

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

Avoids an excessive DOM size


165 elements

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

Speed Index


0.3 s

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

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


1 resource found

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

Time to Interactive


0.3 s

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

First Contentful Paint


0.3 s

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

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.
