First CPU Idle 1.7 s
First CPU Idle marks the first time at which the page's main thread is quiet enough to handle input. [Learn more](https://web.dev/first-cpu-idle/).
Remove unused JavaScript Potential savings of 200 KiB
Remove unused JavaScript to reduce bytes consumed by network activity
JavaScript execution time 0.6 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
Defer offscreen images Potential savings of 4 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive
Speed Index 1.6 s
Speed Index shows how quickly the contents of a page are visibly populated
Minify JavaScript Potential savings of 4 KiB
Minifying JavaScript files can reduce payload sizes and script parse time
Serve static assets with an efficient cache policy 110 resources found
A long cache lifetime can speed up repeat visits to your page
Time to Interactive 1.9 s
Time to interactive is the amount of time it takes for the page to become fully interactive
Links do not have descriptive text 9 links found
Descriptive link text helps search engines understand your content
Max Potential First Input Delay 230 ms

This is the largest contentful element painted within the viewport
Avoid enormous network payloads Total size was 4,672 KiB
Large network payloads cost users real money and are highly correlated with long load times
Cumulative Layout Shift 0.014
Cumulative Layout Shift measures the movement of visible elements within the viewport
Avoids large JavaScript libraries with smaller alternatives 0 large libraries found
Large JavaScript libraries can lead to poor performance. Prefer smaller, functionally equivalent libraries to reduce your bundle size
Avoid large layout shifts 5 elements found
These DOM elements contribute most to the CLS of the page.
Properly size images Potential savings of 109 KiB
Serve images that are appropriately-sized to save cellular data and improve load time
Avoid an excessive DOM size 1,549 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 serving legacy JavaScript to modern browsers Potential savings of 21 KiB
Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. For your bundled JavaScript, adopt a modern script deployment strategy using module/nomodule feature detection to reduce the amount of code shipped to modern browsers, while retaining support for legacy browsers
Avoid long main-thread tasks 4 long tasks found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay
Includes front-end JavaScript libraries with known security vulnerabilities 2 vulnerabilities detected
Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers

Page load is not fast enough on mobile networks Interactive on simulated mobile network at 11.9 s
A fast page load over a cellular network ensures a good mobile user experience
First Contentful Paint 1.2 s
First Contentful Paint marks the time at which the first text or image is painted
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
Serve images in next-gen formats Potential savings of 2,479 KiB
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
Initial server response time was short Root document took 110 ms
Keep the server response time for the main document short because all other requests depend on it
Enable text compression Potential savings of 3 KiB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes
First Meaningful Paint 1.4 s
First Meaningful Paint measures when the primary content of a page is visible
Remove unused CSS Potential savings of 53 KiB
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
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
Efficiently encode images Potential savings of 901 KiB
Optimized images load faster and consume less cellular data
Uses deprecated APIs 1 warning found
Deprecated APIs will eventually be removed from the browser
Total Blocking Time 120 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
Avoid chaining critical requests 28 chains found
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
Largest Contentful Paint 2.5 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Minimize third-party usage Third-party code blocked the main thread for 0 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
