Max Potential First Input Delay
70 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task.

Cumulative Layout Shift
0.022
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
2.7 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
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.
Minimizes main-thread work
1.2 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
Time to Interactive
3.6 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
Avoid enormous network payloads
Total size was 3,901 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Total Blocking Time
30 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
Server Backend Latencies
10 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.
Initial server response time was short
Root document took 440 ms
Keep the server response time for the main document short because all other requests depend on it.
Network Round Trip Times
20 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.
First Contentful Paint
0.7 s
First Contentful Paint marks the time at which the first text or image is painted.
Reduce unused CSS
Est savings of 148 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity.
Reduce unused JavaScript
Est savings of 691 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
Speed Index
4.0 s
Speed Index shows how quickly the contents of a page are visibly populated.
