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

Cumulative Layout Shift
0
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
1.0 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Server Backend Latencies
200 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.
JavaScript execution time
0.4 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
Reduce initial server response time
Root document took 850 ms
Keep the server response time for the main document short because all other requests depend on it.
Avoids enormous network payloads
Total size was 737 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Speed Index
1.6 s
Speed Index shows how quickly the contents of a page are visibly populated.
First Contentful Paint
0.6 s
First Contentful Paint marks the time at which the first text or image is painted.
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
10 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
First Meaningful Paint
0.6 s
First Meaningful Paint measures when the primary content of a page is visible.
Avoid an excessive DOM size
819 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Network Round Trip Times
30 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.
Minimizes main-thread work
1.7 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.
