Core Web Vitals
Max Potential First Input Delay
640 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task.
Cumulative Layout Shift
0.002
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
1.2 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Time to Interactive
15.1 s
Time to interactive is the amount of time it takes for the page to become fully interactive.
Initial server response time was short
Root document took 530 ms

First Contentful Paint
0.3 s
First Contentful Paint marks the time at which the first text or image is painted.
Avoids an excessive DOM size
239 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
First Meaningful Paint
0.4 s
First Meaningful Paint measures when the primary content of a page is visible.
Total Blocking Time
4,570 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
Reduce JavaScript execution time
13.6 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 278 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Speed Index
2.9 s
Speed Index shows how quickly the contents of a page are visibly populated.
Minimize main-thread work
15.3 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
