Desktop Screenshot
Largest Contentful Paint 6.1 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Properly size images Potential savings of 367 KiB
Serve images that are appropriately-sized to save cellular data and improve load time
Serve images in next-gen formats Potential savings of 174 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 144 requests • 1,122 KiB
To set budgets for the quantity and size of page resources, add a budget.json file
Page load is not fast enough on mobile networks Interactive on simulated mobile network at 17.7 s
A fast page load over a cellular network ensures a good mobile user experience
Minify JavaScript Potential savings of 2 KiB
Minifying JavaScript files can reduce payload sizes and script parse 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
JavaScript execution time 0.2 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
Avoid long main-thread tasks 1 long task found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay
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
Avoids enormous network payloads Total size was 1,122 KiB
Large network payloads cost users real money and are highly correlated with long load times
Efficiently encode images Potential savings of 15 KiB
Optimized images load faster and consume less cellular data
Eliminate render-blocking resources Potential savings of 3,670 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
Minify CSS Potential savings of 4 KiB
Minifying CSS files can reduce network payload sizes
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 15 resources found
A long cache lifetime can speed up repeat visits to your page
Avoids an excessive DOM size 516 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 92 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
Total Blocking Time 20 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
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
First Contentful Paint 2.6 s
First Contentful Paint marks the time at which the first text or image is painted
Avoid chaining critical requests 123 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
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
First CPU Idle 3.8 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 4.3 s
Speed Index shows how quickly the contents of a page are visibly populated
First Meaningful Paint 3.8 s
First Meaningful Paint measures when the primary content of a page is visible
Max Potential First Input Delay 50 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
Remove unused JavaScript Potential savings of 59 KiB
Remove unused JavaScript to reduce bytes consumed by network activity
Includes front-end JavaScript libraries with known security vulnerabilities 3 vulnerabilities detected
Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers
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
Time to Interactive 6.0 s
Time to interactive is the amount of time it takes for the page to become fully interactive
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

Mobile

Mobile Screenshot
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
Time to Interactive 16.3 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 at 16.3 s
A fast page load over a cellular network ensures a good mobile user experience
Tap targets are not sized appropriately 71% 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
Largest Contentful Paint 16.7 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Efficiently encode images Potential savings of 15 KiB
Optimized images load faster and consume less cellular data
