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

Cumulative Layout Shift
0.024
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
1.3 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Avoids an excessive DOM size
151 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Time to Interactive
1.3 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
Uses efficient cache policy on static assets
4 resources found
A long cache lifetime can speed up repeat visits to your page.
Avoids enormous network payloads
Total size was 105 KiB
Large network payloads cost users real money and are highly correlated with long load times.
First Contentful Paint
1.3 s
First Contentful Paint marks the time at which the first text or image is painted.
Eliminate render-blocking resources
Potential savings of 800 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.
Speed Index
1.7 s
Speed Index shows how quickly the contents of a page are visibly populated.
Network Round Trip Times
90 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.
Initial server response time was short
Root document took 160 ms
Keep the server response time for the main document short because all other requests depend on it.
Minimizes main-thread work
0.1 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
Server Backend Latencies
90 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 Meaningful Paint
1.3 s
First Meaningful Paint measures when the primary content of a page is visible.
Notes
* These are assets not hosted on the same domain e.g. tracking scripts, iframe embeds, or files hosted on a CDN.
These measurements are for each new visitor, for returning visitors the footprint would be lower based on caching mechanisms.
