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.
Largest Contentful Paint
0.4 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Enable text compression
Potential savings of 93 KiB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes.
Total Blocking Time
20 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 300 ms
Keep the server response time for the main document short because all other requests depend on it.
Speed Index
0.6 s
Speed Index shows how quickly the contents of a page are visibly populated.
Minimizes main-thread work
0.3 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 106 KiB
Large network payloads cost users real money and are highly correlated with long load times.
First Meaningful Paint
0.4 s
First Meaningful Paint measures when the primary content of a page is visible.
JavaScript execution time
0.0 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
73 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Time to Interactive
0.5 s
Time to interactive is the amount of time it takes for the page to become fully interactive.
First Contentful Paint
0.4 s
First Contentful Paint marks the time at which the first text or image is painted.
