Desktop

Cumulative Layout Shift 0.096

Cumulative Layout Shift measures the movement of visible elements within the viewport

Serve static assets with an efficient cache policy 32 resources found

A long cache lifetime can speed up repeat visits to your page

Speed Index 2.1 s

Speed Index shows how quickly the contents of a page are visibly populated

Reduce the impact of third-party code Third-party code blocked the main thread for 470 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

Serve images in next-gen formats Potential savings of 307 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

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

Total Blocking Time 310 ms

Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds

Reduce initial server response time Root document took 610 ms

Keep the server response time for the main document short because all other requests depend on it

Includes front-end JavaScript libraries with known security vulnerabilities 4 vulnerabilities detected

Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers

First Meaningful Paint 1.1 s

First Meaningful Paint measures when the primary content of a page is visible

Avoid large layout shifts 5 elements found

These DOM elements contribute most to the CLS of the page.

Remove unused CSS Potential savings of 15 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

Reduce JavaScript execution time 2.2 s

Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this

Eliminate render-blocking resources Potential savings of 0 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 160 ms

The maximum potential First Input Delay that your users could experience is the duration of the longest task

Avoids an excessive DOM size 636 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)

Largest Contentful Paint 1.7 s

Largest Contentful Paint marks the time at which the largest text or image is painted

First Contentful Paint 1.0 s

First Contentful Paint marks the time at which the first text or image is painted

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 element 1 element found

This is the largest contentful element painted within the viewport

Avoid long main-thread tasks 9 long tasks found

Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay

Properly size images Potential savings of 13 KiB

Serve images that are appropriately-sized to save cellular data and improve load time

Minimize main-thread work 3.7 s

Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this

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

Avoids enormous network payloads Total size was 2,154 KiB

Large network payloads cost users real money and are highly correlated with long load times

First CPU Idle 3.5 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 98 KiB

Remove unused JavaScript to reduce 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

Estimated Input Latency 50 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

Keep request counts low and transfer sizes small 202 requests • 2,154 KiB

To set budgets for the quantity and size of page resources, add a budget.json file

Page load is not fast enough on mobile networks Interactive on simulated mobile network at 16.5 s

A fast page load over a cellular network ensures a good mobile user experience

Time to Interactive 3.8 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 0 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
