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

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

Serve static assets with an efficient cache policy 41 resources found

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

Cumulative Layout Shift 0.036

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

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

Speed Index 1.8 s

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

First Meaningful Paint 0.9 s

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

Efficiently encode images Potential savings of 6 KiB

Optimized images load faster and consume less cellular data

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 JavaScript Potential savings of 182 KiB

Remove unused JavaScript to reduce bytes consumed by network activity

Avoids enormous network payloads Total size was 1,344 KiB

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

First Contentful Paint 0.6 s

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

Largest Contentful Paint 2.4 s

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

Time to Interactive 2.3 s

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

Properly size images Potential savings of 39 KiB

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

Serve images in next-gen formats Potential savings of 10 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

Keep request counts low and transfer sizes small 52 requests • 1,344 KiB

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

Minimizes main-thread work 1.3 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

Total Blocking Time 30 ms

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

Defer offscreen images Potential savings of 13 KiB

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

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

First CPU Idle 1.3 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/).

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

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

Initial server response time was short Root document took 130 ms

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

Avoid chaining critical requests 9 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 an excessive DOM size 1,173 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)

Remove unused CSS Potential savings of 197 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

Preload key requests Potential savings of 630 ms

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

Avoid large layout shifts 1 element found

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

JavaScript execution time 0.4 s

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

Max Potential First Input Delay 120 ms

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

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

Mobile

Avoids enormous network payloads Total size was 1,332 KiB

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

Max Potential First Input Delay 680 ms

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

Eliminate render-blocking resources Potential savings of 2,480 ms

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

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

Tap targets are sized appropriately 100% appropriately sized tap targets

Interactive elements like buttons and links should be large enough (48x48px), and have enough space around them, to be easy enough to tap without overlapping onto other elements

Time to Interactive 9.4 s
