Desktop

Desktop Screenshot
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
Avoid large layout shifts 3 elements found
These DOM elements contribute most to the CLS of the page.
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
Largest Contentful Paint element 1 element found
This is the largest contentful element painted within the viewport
Eliminate render-blocking resources Potential savings of 80 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
Keep request counts low and transfer sizes small 68 requests • 1,423 KiB
To set budgets for the quantity and size of page resources, add a budget.json file
Serve static assets with an efficient cache policy 4 resources found
A long cache lifetime can speed up repeat visits to your page
First Contentful Paint 1.1 s
First Contentful Paint marks the time at which the first text or image is painted
Speed Index 1.1 s
Speed Index shows how quickly the contents of a page are visibly populated
First CPU Idle 2.5 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/).
Avoid an excessive DOM size 1,548 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 2.7 s
Time to interactive is the amount of time it takes for the page to become fully interactive
First Meaningful Paint 1.5 s
First Meaningful Paint measures when the primary content of a page is visible
Properly size images Potential savings of 55 KiB
Serve images that are appropriately-sized to save cellular data and improve load time
Remove unused JavaScript Potential savings of 271 KiB
Remove unused JavaScript to reduce bytes consumed by network activity
Max Potential First Input Delay 290 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
Defer offscreen images Potential savings of 38 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive
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
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
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
Avoid long main-thread tasks 2 long tasks found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay
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
Initial server response time was short Root document took 170 ms
Keep the server response time for the main document short because all other requests depend on it
Avoid chaining critical requests 8 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
Page load is not fast enough on mobile networks Interactive on simulated mobile network at 12.6 s
A fast page load over a cellular network ensures a good mobile user experience
Avoids enormous network payloads Total size was 1,423 KiB
Large network payloads cost users real money and are highly correlated with long load times
User Timing marks and measures 11 user timings
Consider instrumenting your app with the User Timing API to measure your app's real-world performance during key user experiences
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
Largest Contentful Paint 2.8 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Total Blocking Time 130 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds

Time to Interactive 13.3 s
Time to interactive is the amount of time it takes for the page to become fully interactive
Speed Index 5.4 s
Speed Index shows how quickly the contents of a page are visibly populated
Defer offscreen images Potential savings of 140 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive
Page load is not fast enough on mobile networks Interactive at 13.3 s
A fast page load over a cellular network ensures a good mobile user experience
Initial server response time was short Root document took 120 ms
Keep the server response time for the main document short because all other requests depend on it
First Contentful Paint 5.2 s
First Contentful Paint marks the time at which the first text or image is painted
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
Minimize third-party usage Third-party code blocked the main thread for 70 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 (3G) 14190 ms
First Contentful Paint 3G marks the time at which the first text or image is painted while on a 3G network

Remove unused JavaScript to reduce bytes consumed by network activity
Avoid long main-thread tasks 15 long tasks found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay

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
Total Blocking Time 1,170 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
Estimated Input Latency 620 ms
