Avoid chaining critical requests 6 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 long main-thread tasks 1 long task found

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

Avoid large layout shifts 5 elements found

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

JavaScript execution time 0.2 s

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

Speed Index 1.0 s

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

Preload key requests Potential savings of 230 ms

Consider using `<link rel=preload>` to prioritize fetching resources that are currently requested later in page load

Total Blocking Time 10 ms

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

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

Remove unused JavaScript Potential savings of 100 KiB

Remove unused JavaScript to reduce bytes consumed by network activity

Serve static assets with an efficient cache policy 9 resources found

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

Avoids enormous network payloads Total size was 332 KiB

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

Remove unused CSS Potential savings of 34 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

Initial server response time was short Root document took 440 ms

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

Avoids an excessive DOM size 145 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)

Keep request counts low and transfer sizes small 21 requests • 332 KiB

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

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

Minimizes main-thread work 0.4 s

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

Largest Contentful Paint element 1 element found

This is the largest contentful element painted within the viewport

Time to Interactive 0.8 s

Time to interactive is the amount of time it takes for the page to become fully interactive

Largest Contentful Paint 0.7 s

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

Max Potential First Input Delay 60 ms

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

First CPU Idle 0.8 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/).

Web app manifest or service worker do not meet the installability requirements 1 reason

Service worker is the technology that enables your app to use many Progressive Web App features, such as offline, add to homescreen, and push notifications. With proper service worker and manifest implementations, browsers can proactively prompt users to add your app to their homescreen, which can lead to higher engagement

Eliminate render-blocking resources Potential savings of 440 ms

Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles

Cumulative Layout Shift 0.047

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

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

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

First Contentful Paint 0.7 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

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

First Meaningful Paint 0.7 s

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