Desktop Speed Score

Desktop Screenshot
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
Preload Largest Contentful Paint image Potential savings of 350 ms
Preload the image used by the LCP element in order to improve your LCP time
Serve images in next-gen formats Potential savings of 8 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
Properly size images Potential savings of 80 KiB
Serve images that are appropriately-sized to save cellular data and improve load time
First Contentful Paint 0.6 s
First Contentful Paint marks the time at which the first 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
Remove unused CSS Potential savings of 175 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
Total Blocking Time 30 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
Avoids enormous network payloads Total size was 528 KiB
Large network payloads cost users real money and are highly correlated with long load times
Eliminate render-blocking resources Potential savings of 290 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
Avoid an excessive DOM size 940 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)
Serve static assets with an efficient cache policy 10 resources found
A long cache lifetime can speed up repeat visits to your page
Largest Contentful Paint 1.3 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Keep request counts low and transfer sizes small 42 requests • 528 KiB
To set budgets for the quantity and size of page resources, add a budget.json file
Largest Contentful Paint element 1 element found
This is the largest contentful element painted within the viewport
Preload key requests Potential savings of 600 ms
Consider using `<link rel=preload>` to prioritize fetching resources that are currently requested later in page load
Avoid long main-thread tasks 2 long tasks found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay
Speed Index 0.8 s
Speed Index shows how quickly the contents of a page are visibly populated
Max Potential First Input Delay 110 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
Estimated Input Latency 10 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
Cumulative Layout Shift 0.008
Cumulative Layout Shift measures the movement of visible elements within the viewport
Avoid large layout shifts 5 elements found
These DOM elements contribute most to the CLS of the page.
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
Time to Interactive 1.0 s
Time to interactive is the amount of time it takes for the page to become fully interactive
Avoid serving legacy JavaScript to modern browsers Potential savings of 11 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
First CPU Idle 0.9 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 21 KiB
Remove unused JavaScript to reduce bytes consumed by network activity
First Meaningful Paint 0.8 s
First Meaningful Paint measures when the primary content of a page is visible
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
Avoid chaining critical requests 24 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
Avoid non-composited animations 1 animated element found
Animations which are not composited can be janky and increase CLS
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
Minimizes main-thread work 0.7 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
