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/).

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
