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

Cumulative Layout Shift
0
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
0.4 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Server Backend Latencies
140 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.
First Contentful Paint
0.4 s
First Contentful Paint marks the time at which the first text or image is painted.
Time to Interactive
0.7 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 2,827 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Initial server response time was short
Root document took 30 ms
Keep the server response time for the main document short because all other requests depend on it.
Network Round Trip Times
10 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.
Minimizes main-thread work
0.5 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
JavaScript execution time
0.1 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
Speed Index
4.3 s
Speed Index shows how quickly the contents of a page are visibly populated.
Total Blocking Time
20 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
Notes
* 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.
