Max Potential First Input Delay
50 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
1.1 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Avoids an excessive DOM size
351 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Time to Interactive
1.1 s
Time to Interactive is the amount of time it takes for the page to become fully interactive.
Minimizes main-thread work
0.6 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.
Total Blocking Time
0 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
Properly size images
Potential savings of 166 KiB
Serve images that are appropriately-sized to save cellular data and improve load time.
Speed Index
0.7 s
Speed Index shows how quickly the contents of a page are visibly populated.
Avoids enormous network payloads
Total size was 434 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 90 ms
Keep the server response time for the main document short because all other requests depend on it.
Reduce unused CSS
Potential savings of 92 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity.
Server Backend Latencies
0 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.
Serve static assets with an efficient cache policy
10 resources found
A long cache lifetime can speed up repeat visits to your page.
Eliminate render-blocking resources
Potential savings of 220 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.
Network Round Trip Times
0 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
0.6 s
First Contentful Paint marks the time at which the first text or image is painted.
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.
