Core Web Vitals
Max Potential First Input Delay
70 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task.
Learn more about the Maximum Potential First Input Delay metric
Cumulative Layout Shift
0.355
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
1.5 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
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.
Time to Interactive
1.5 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
Avoid serving legacy JavaScript to modern browsers
Potential savings of 8 KiB
Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. For your bundled JavaScript, adopt a modern script deployment strategy using module/nomodule feature detection to reduce the amount of code shipped to modern browsers, while retaining support for legacy browsers.
Avoids an excessive DOM size
378 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Initial server response time was short
Root document took 480 ms
Keep the server response time for the main document short because all other requests depend on it.
Reduce unused JavaScript
Potential savings of 75 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
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.
Serve static assets with an efficient cache policy
2 resources found
A long cache lifetime can speed up repeat visits to your page.
Avoids enormous network payloads
Total size was 1,357 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Total Blocking Time
40 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
First Contentful Paint
0.6 s
First Contentful Paint marks the time at which the first text or image is painted.
Minimizes main-thread work
1.1 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
JavaScript execution time
0.3 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
Speed Index
1.7 s
Speed Index shows how quickly the contents of a page are visibly populated.
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.
