Max Potential First Input Delay 100 ms

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

Speed Index 4.1 s

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

Remove unused JavaScript Potential savings of 61 KiB

Remove unused JavaScript to reduce bytes consumed by network activity

First Meaningful Paint 1.8 s

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

Largest Contentful Paint 4.2 s

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

Estimated Input Latency 20 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

Total Blocking Time 120 ms

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

Minify CSS Potential savings of 3 KiB

Minifying CSS files can reduce network payload sizes

Avoids an excessive DOM size 439 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)

Cumulative Layout Shift 0.562

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

Avoids enormous network payloads Total size was 1,724 KiB

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

Keep request counts low and transfer sizes small 90 requests • 1,724 KiB

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

Uses efficient cache policy on static assets 2 resources found

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

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

Defer offscreen images Potential savings of 103 KiB

Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive

Minimizes main-thread work 2.0 s

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

Remove unused CSS Potential savings of 181 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

Includes front-end JavaScript libraries with known security vulnerabilities 10 vulnerabilities detected

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

Reduce initial server response time Root document took 760 ms

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

JavaScript execution time 1.0 s

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

Avoid large layout shifts 5 elements found

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

Efficiently encode images Potential savings of 12 KiB

Optimized images load faster and consume less cellular data

Largest Contentful Paint element 1 element found

This is the largest contentful element painted within the viewport

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

Time to Interactive 4.0 s

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

Page load is not fast enough on mobile networks Interactive on simulated mobile network at 14.5 s

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

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

Serve images in next-gen formats Potential savings of 88 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 7 KiB

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

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 1.8 s

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

Avoid long main-thread tasks 5 long tasks found

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

Avoid chaining critical requests 50 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

Eliminate render-blocking resources Potential savings of 2,270 ms

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

Preload key requests Potential savings of 130 ms

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

First CPU Idle 2.3 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/).

Mobile

First Contentful Paint (3G) 11123 ms

First Contentful Paint 3G marks the time at which the first text or image is painted while on a 3G network

Document uses legible font sizes 100% 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

Avoids enormous network payloads Total size was 1,738 KiB

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

Total Blocking Time 1,300 ms

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

Minimize main-thread work 6.7 s

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