Avoid chaining critical requests 24 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 Meaningful Paint 2.6 s
First Meaningful Paint measures when the primary content of a page is visible
Serve static assets with an efficient cache policy 58 resources found
A long cache lifetime can speed up repeat visits to your page
Total Blocking Time 80 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
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
Initial server response time was short Root document took 520 ms
Keep the server response time for the main document short because all other requests depend on it
Cumulative Layout Shift 0.147
Cumulative Layout Shift measures the movement of visible elements within the viewport
First CPU Idle 2.6 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).
Speed Index 2.5 s
Speed Index shows how quickly the contents of a page are visibly populated
Eliminate render-blocking resources Potential savings of 2,350 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
Largest Contentful Paint 5.6 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Keep request counts low and transfer sizes small 71 requests • 5,683 KB
To set budgets for the quantity and size of page resources, add a budget.json file
Time to Interactive 3.0 s
Time to interactive is the amount of time it takes for the page to become fully interactive
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
Remove unused JavaScript Potential savings of 527 KB
Remove unused JavaScript to reduce bytes consumed by network activity
Remove unused CSS Potential savings of 986 KB
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
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
Avoid enormous network payloads Total size was 5,683 KB
Large network payloads cost users real money and are highly correlated with long load times
Properly size images Potential savings of 1,124 KB
Serve images that are appropriately-sized to save cellular data and improve load time
Serve images in next-gen formats Potential savings of 2,999 KB
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
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
Largest Contentful Paint element 1 element found
This is the element that was identified as the Largest Contentful Paint
Page load is not fast enough on mobile networks Interactive on simulated mobile network at 15.4 s
A fast page load over a cellular network ensures a good mobile user experience
Efficiently encode images Potential savings of 1,532 KB
Optimized images load faster and consume less cellular data
Minimize third-party usage Third-party code blocked the main thread for 20 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
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
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
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
Enable text compression Potential savings of 1,051 KB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes
Avoid large layout shifts 5 elements found
These DOM elements contribute most to the CLS of the page.
Minify JavaScript Potential savings of 39 KB
Minifying JavaScript files can reduce payload sizes and script parse time
Avoids an excessive DOM size 706 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)
First Contentful Paint 2.3 s
First Contentful Paint marks the time at which the first text or image is painted

Minify JavaScript Potential savings of 39 KB
Minifying JavaScript files can reduce payload sizes and script parse time
Document uses legible font sizes 86.55% 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
