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
1.0 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Time to Interactive
1.3 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
First Meaningful Paint
0.8 s
First Meaningful Paint measures when the primary content of a page is visible.
Total Blocking Time
100 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
Properly size images
Potential savings of 157 KiB
Serve images that are appropriately-sized to save cellular data and improve load time.
First Contentful Paint
0.8 s
First Contentful Paint marks the time at which the first text or image is painted.
Initial server response time was short
Root document took 200 ms
Keep the server response time for the main document short because all other requests depend on it.
Serve static assets with an efficient cache policy
1 resource found
A long cache lifetime can speed up repeat visits to your page.
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.
Avoids enormous network payloads
Total size was 1,057 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Server Backend Latencies
510 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.
Avoids an excessive DOM size
686 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Speed Index
1.9 s
Speed Index shows how quickly the contents of a page are visibly populated.
JavaScript execution time
0.5 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
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.
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.
