Total Blocking Time 130 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 164 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive
Avoids enormous network payloads Total size was 2,453 KiB
Large network payloads cost users real money and are highly correlated with long load times
Serve static assets with an efficient cache policy 83 resources found
A long cache lifetime can speed up repeat visits to your page
Page load is not fast enough on mobile networks Interactive on simulated mobile network at 19.6 s
A fast page load over a cellular network ensures a good mobile user experience
User Timing marks and measures 4 user timings
Consider instrumenting your app with the User Timing API to measure your app's real-world performance during key user experiences
Avoid long main-thread tasks 8 long tasks found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay
Remove unused CSS Potential savings of 73 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
First Contentful Paint 1.1 s
First Contentful Paint marks the time at which the first text or image is painted
Speed Index 3.9 s
Speed Index shows how quickly the contents of a page are visibly populated
First CPU Idle 3.1 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/).
Minify JavaScript Potential savings of 2 KiB
Minifying JavaScript files can reduce payload sizes and script parse time
Cumulative Layout Shift 0.465
Cumulative Layout Shift measures the movement of visible elements within the viewport
Minimize main-thread work 2.1 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this

Optimized images load faster and consume less cellular data
Minify CSS Potential savings of 7 KiB
Minifying CSS files can reduce network payload sizes
Eliminate render-blocking resources Potential savings of 740 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
Avoids an excessive DOM size 716 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)
Time to Interactive 4.9 s
Time to interactive is the amount of time it takes for the page to become fully interactive
Largest Contentful Paint 5.1 s

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
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
Serve images in next-gen formats Potential savings of 495 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 121 requests • 2,454 KiB
To set budgets for the quantity and size of page resources, add a budget.json file
Properly size images Potential savings of 250 KiB

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
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
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 chaining critical requests 47 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
JavaScript execution time 0.8 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
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.
Largest Contentful Paint element 1 element found
This is the largest contentful element painted within the viewport
