Core Web Vitals
Max Potential First Input Delay
230 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
Largest Contentful Paint
0.8 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
First Contentful Paint
0.5 s
First Contentful Paint marks the time at which the first text or image is painted.
Avoid an excessive DOM size
1,707 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Speed Index
1.2 s
Speed Index shows how quickly the contents of a page are visibly populated.
Total Blocking Time
350 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
Server Backend Latencies
10 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
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.
Time to Interactive
2.1 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
Minimize main-thread work
2.5 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
Avoids enormous network payloads
Total size was 1,238 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Initial server response time was short
Root document took 280 ms
Keep the server response time for the main document short because all other requests depend on it.
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.
Reduce unused JavaScript
Potential savings of 292 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
Serve static assets with an efficient cache policy
2 resources found
A long cache lifetime can speed up repeat visits to your page.
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.
