Core Web Vitals
Max Potential First Input Delay
40 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
0.5 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
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.
Speed Index
0.7 s
Speed Index shows how quickly the contents of a page are visibly populated.
Time to Interactive
0.5 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
JavaScript execution time
0.1 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
Initial server response time was short
Root document took 420 ms
Keep the server response time for the main document short because all other requests depend on it.
First Contentful Paint
0.4 s
First Contentful Paint marks the time at which the first text or image is painted.
Avoids enormous network payloads
Total size was 375 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Serve static assets with an efficient cache policy
2 resources found
A long cache lifetime can speed up repeat visits to your page.
Avoids an excessive DOM size
507 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Minimizes main-thread work
0.5 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
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.
