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

Cumulative Layout Shift
0.387
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
1.4 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
First Contentful Paint
0.8 s
First Contentful Paint marks the time at which the first text or image is painted.
Minify JavaScript
Est savings of 12 KiB
Minifying JavaScript files can reduce payload sizes and script parse time.
Speed Index
1.9 s
Speed Index shows how quickly the contents of a page are visibly populated.
Network Round Trip Times
10 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.
Minimize main-thread work
3.4 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 640 ms
Keep the server response time for the main document short because all other requests depend on it.
Total Blocking Time
70 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
Time to Interactive
2.2 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
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.
Reduce JavaScript execution time
1.5 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
Avoid enormous network payloads
Total size was 5,178 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Switch to green hosting
One of the easiest things to do that instantly reduces your impact.
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.
