Largest Contentful Paint marks the time at which the largest text or image is painted.
1.0 s
First Contentful Paint marks the time at which the first text or image is painted.
Root document took 1,720 ms
Keep the server response time for the main document short because all other requests depend on it.
240 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.
2.1 s
Speed Index shows how quickly the contents of a page are visibly populated.
1.3 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
707 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
10 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.

Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
Potential savings of 40 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.
1.0 s
First Meaningful Paint measures when the primary content of a page is visible.
Potential savings of 30 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity.
0.3 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
Potential savings of 350 ms
If the LCP element is dynamically added to the page, you should preload the image in order to improve LCP.
Potential savings of 105 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.

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.
One of the easiest things to do that instantly reduces your impact.

* 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.
