Desktop Screenshot
Cumulative Layout Shift 0.043
Cumulative Layout Shift measures the movement of visible elements within the viewport
Minimizes main-thread work 0.8 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
Properly size images Potential savings of 907 KiB
Serve images that are appropriately-sized to save cellular data and improve load time
Avoid an excessive DOM size 877 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 chaining critical requests 29 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
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
Avoid non-composited animations 1 animated element found
Animations which are not composited can be janky and increase CLS
Avoids enormous network payloads Total size was 1,710 KiB
Large network payloads cost users real money and are highly correlated with long load times
Reduce unused JavaScript Potential savings of 75 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity
Avoid large layout shifts 3 layout shifts found
These are the largest layout shifts observed on the page. Each table item represents a single layout shift, and shows the element that shifted the most. Below each item are possible root causes that led to the layout shift. Some of these layout shifts may not be included in the CLS metric value due to [windowing](https://web.dev/articles/cls#what_is_cls)
Largest Contentful Paint element 1,630 ms
This is the largest contentful element painted within the viewport
Largest Contentful Paint 1.6 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Speed Index 0.9 s
Speed Index shows how quickly the contents of a page are visibly populated
Avoid serving legacy JavaScript to modern browsers Potential savings of 23 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
Reduce unused CSS Potential savings of 11 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity
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
User Timing marks and measures 3 user timings
Consider instrumenting your app with the User Timing API to measure your app's real-world performance during key user experiences
Time to Interactive 1.6 s
Time to Interactive is the amount of time it takes for the page to become fully interactive
Initial server response time was short Root document took 240 ms
Keep the server response time for the main document short because all other requests depend on it
Server Backend Latencies 20 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
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
First Contentful Paint 0.9 s
First Contentful Paint marks the time at which the first text or image is painted
Serve static assets with an efficient cache policy 18 resources found
A long cache lifetime can speed up repeat visits to your page
Total Blocking Time 0 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
Eliminate render-blocking resources Potential savings of 240 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
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
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
Avoid long main-thread tasks 1 long task found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay
User Timing marks and measures 3 user timings
Consider instrumenting your app with the User Timing API to measure your app's real-world performance during key user experiences
Time to Interactive 8.3 s
Time to Interactive is the amount of time it takes for the page to become fully interactive
Cumulative Layout Shift 0.126
Cumulative Layout Shift measures the movement of visible elements within the viewport
Avoid non-composited animations 1 animated element found
Animations which are not composited can be janky and increase CLS
Document uses legible font sizes 99.18% legible text
Font sizes less than 12px are too small to be legible and require mobile visitors to “pinch to zoom” in order to read. Strive to have >60% of page text ≥12px
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
First Contentful Paint 6.2 s
First Contentful Paint marks the time at which the first text or image is painted

Initial server response time was short Root document took 270 ms
Keep the server response time for the main document short because all other requests depend on it
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
Avoid an excessive DOM size 871 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)
