Core Web Vitals
Max Potential First Input Delay
30 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task.

Cumulative Layout Shift
0.013
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
First Contentful Paint
0.4 s
First Contentful Paint marks the time at which the first text or image is painted.
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.
Avoids enormous network payloads
Total size was 187 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Time to Interactive
0.6 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
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.
Initial server response time was short
Root document took 60 ms
Keep the server response time for the main document short because all other requests depend on it.
Avoids an excessive DOM size
443 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Reduce unused CSS
Est 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.
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.
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.
Speed Index
0.5 s
Speed Index shows how quickly the contents of a page are visibly populated.
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.
