Serve images that are appropriately-sized to save cellular data and improve load time
First Contentful Paint 1.2 s
First Contentful Paint marks the time at which the first text or image is painted
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
Reduce JavaScript execution time 2.6 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 190 ms
Keep the server response time for the main document short because all other requests depend on it
Largest Contentful Paint 3.5 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Enable text compression Potential savings of 75 KB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes
Avoid enormous network payloads Total size was 4,174 KB
Large network payloads cost users real money and are highly correlated with long load times
Speed Index 2.4 s
Speed Index shows how quickly the contents of a page are visibly populated
First Meaningful Paint 1.4 s
First Meaningful Paint measures when the primary content of a page is visible
Eliminate render-blocking resources Potential savings of 120 ms

Remove unused CSS Potential savings of 125 KB
Remove dead rules from stylesheets and defer the loading of CSS not used for above-the-fold content to reduce unnecessary bytes consumed by network activity
Serve images in next-gen formats Potential savings of 1,116 KB
Image formats like JPEG 2000, JPEG XR, and WebP often provide better compression than PNG or JPEG, which means faster downloads and less data consumption
Reduce the impact of third-party code Third-party code blocked the main thread for 960 ms
Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading
Estimated Input Latency 90 ms
Estimated Input Latency is an estimate of how long your app takes to respond to user input, in milliseconds, during the busiest 5s window of page load. If your latency is higher than 50 ms, users may perceive your app as laggy

The Critical Request Chains below show you what resources are loaded with a high priority. Consider reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load
Avoid an excessive DOM size 1,451 elements
A large DOM will increase memory usage, cause longer [style calculations](https://developers.google.com/web/fundamentals/performance/rendering/reduce-the-scope-and-complexity-of-style-calculations), and produce costly [layout reflows](https://developers.google.com/speed/articles/reflow)
Avoid large layout shifts No elements found
These DOM elements contribute most to the CLS of the page.

The maximum potential First Input Delay that your users could experience is the duration of the longest task
Minify CSS Potential savings of 19 KB
Minifying CSS files can reduce network payload sizes
Total Blocking Time 670 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
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
Efficiently encode images Potential savings of 501 KB
Optimized images load faster and consume less cellular data
Time to Interactive 4.7 s
Time to interactive is the amount of time it takes for the page to become fully interactive
Includes front-end JavaScript libraries with known security vulnerabilities 4 vulnerabilities detected
