Avoid chaining critical requests 5 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
First Contentful Paint 0.5 s
First Contentful Paint marks the time at which the first text or image is painted
Time to Interactive 0.6 s
Time to interactive is the amount of time it takes for the page to become fully interactive
Total Blocking Time 0 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
First Meaningful Paint 0.6 s
First Meaningful Paint measures when the primary content of a page is visible
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
Cumulative Layout Shift 1.111
Cumulative Layout Shift measures the movement of visible elements within the viewport
Properly size images Potential savings of 424 KiB
Serve images that are appropriately-sized to save cellular data and improve load time
Largest Contentful Paint 1.7 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Remove unused CSS Potential savings of 25 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
Avoids enormous network payloads Total size was 1,060 KiB
Large network payloads cost users real money and are highly correlated with long load times
Remove unused JavaScript Potential savings of 85 KiB
Remove unused JavaScript to reduce bytes consumed by network activity
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
Serve images in next-gen formats Potential savings of 213 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
Initial server response time was short Root document took 210 ms
Keep the server response time for the main document short because all other requests depend on it
JavaScript execution time 0.5 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
Minify JavaScript Potential savings of 6 KiB
Minifying JavaScript files can reduce payload sizes and script parse time
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
First CPU Idle 0.6 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/).
Minimizes main-thread work 0.9 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
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
Keep request counts low and transfer sizes small 36 requests • 1,060 KiB
To set budgets for the quantity and size of page resources, add a budget.json file
Speed Index 1.3 s
Speed Index shows how quickly the contents of a page are visibly populated
Includes front-end JavaScript libraries with known security vulnerabilities 9 vulnerabilities detected
Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers
Avoids an excessive DOM size 526 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)
Max Potential First Input Delay 30 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
Serve static assets with an efficient cache policy 26 resources found
A long cache lifetime can speed up repeat visits to your page
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
Eliminate render-blocking resources Potential savings of 240 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
