Core Web Vitals
Max Potential First Input Delay
60 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task.
Learn more about the Maximum Potential First Input Delay metric
Largest Contentful Paint
0.7 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
First Meaningful Paint
0.4 s
First Meaningful Paint measures when the primary content of a page is visible.
Serve images in next-gen formats
Potential savings of 28 KiB
Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption.
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
0.4 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
Initial server response time was short
Root document took 90 ms
Keep the server response time for the main document short because all other requests depend on it.
Speed Index
0.5 s
Speed Index shows how quickly the contents of a page are visibly populated.
First Contentful Paint
0.4 s
First Contentful Paint marks the time at which the first text or image is painted.
Server Backend Latencies
40 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.
Properly size images
Potential savings of 34 KiB
Serve images that are appropriately-sized to save cellular data and improve load time.
Avoids enormous network payloads
Total size was 421 KiB
Large network payloads cost users real money and are highly correlated with long load times.
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.
Avoid an excessive DOM size
1,074 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Time to Interactive
0.4 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
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.
