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

Cumulative Layout Shift
0.186
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
Serve static assets with an efficient cache policy
1 resource found
A long cache lifetime can speed up repeat visits to your page.
First Meaningful Paint
1.0 s
First Meaningful Paint measures when the primary content of a page is visible.
Speed Index
2.4 s
Speed Index shows how quickly the contents of a page are visibly populated.
Initial server response time was short
Root document took 540 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 1,011 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Server Backend Latencies
130 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.
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.
First Contentful Paint
0.5 s
First Contentful Paint marks the time at which the first text or image is painted.
Total Blocking Time
1,260 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
Minimize main-thread work
3.7 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
Reduce JavaScript execution time
2.4 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
Time to Interactive
2.5 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
Avoid an excessive DOM size
1,302 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
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.
