Core Web Vitals
Max Potential First Input Delay
80 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task.
Cumulative Layout Shift
0.001
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
0.6 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Speed Index
0.4 s
Speed Index shows how quickly the contents of a page are visibly populated.
Minimizes main-thread work
0.4 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
Avoids an excessive DOM size
139 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
JavaScript execution time
0.2 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
Total Blocking Time
30 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
Initial server response time was short
Root document took 150 ms
Keep the server response time for the main document short because all other requests depend on it.
Avoids enormous network payloads
Total size was 559 KiB
Large network payloads cost users real money and are highly correlated with long load times.
First Meaningful Paint
0.6 s
First Meaningful Paint measures when the primary content of a page is visible.
First Contentful Paint
0.4 s
First Contentful Paint marks the time at which the first text or image is painted.
Time to Interactive
0.8 s
Time to interactive is the amount of time it takes for the page to become fully interactive.
Reduce unused JavaScript
Potential savings of 135 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
