Desktop

Desktop Screenshot
Cumulative Layout Shift 0.009
Cumulative Layout Shift measures the movement of visible elements within the viewport
Avoids enormous network payloads Total size was 103 KiB
Large network payloads cost users real money and are highly correlated with long load times
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 serving legacy JavaScript to modern browsers Potential savings of 6 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
Avoids an excessive DOM size 218 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 24 resources found
A long cache lifetime can speed up repeat visits to your page
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
Total Blocking Time 0 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
Speed Index 1.0 s
Speed Index shows how quickly the contents of a page are visibly populated
Largest Contentful Paint 0.8 s
Largest Contentful Paint marks the time at which the largest 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
Does not use HTTPS 26 insecure requests found
All sites should be protected with HTTPS, even ones that don't handle sensitive data. This includes avoiding [mixed content](https://developers.google.com/web/fundamentals/security/prevent-mixed-content/what-is-mixed-content), where some resources are loaded over HTTP despite the initial request being servedover HTTPS. HTTPS prevents intruders from tampering with or passively listening in on the communications between your app and your users, and is a prerequisite for HTTP/2 and many new web platform APIs
Minimizes main-thread work 0.2 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
First CPU Idle 0.7 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/).
Avoid chaining critical requests 12 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
Minify JavaScript Potential savings of 15 KiB
Minifying JavaScript files can reduce payload sizes and script parse time
Keep request counts low and transfer sizes small 26 requests • 103 KiB
To set budgets for the quantity and size of page resources, add a budget.json file
Max Potential First Input Delay 30 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
First Meaningful Paint 0.7 s
First Meaningful Paint measures when the primary content of a page is visible
Avoid large layout shifts 3 elements found
These DOM elements contribute most to the CLS of the page.
Eliminate render-blocking resources Potential savings of 710 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
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
First Contentful Paint 0.7 s
First Contentful Paint marks the time at which the first text or image is painted
JavaScript execution time 0.0 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
Time to Interactive 0.7 s
Time to interactive is the amount of time it takes for the page to become fully interactive
Largest Contentful Paint element 1 element found
This is the largest contentful element painted within the viewport
Initial server response time was short Root document took 350 ms
Keep the server response time for the main document short because all other requests depend on it
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
Links do not have descriptive text 1 link found
Descriptive link text helps search engines understand your content
