Desktop

Desktop Screenshot
Minimizes main-thread work 1.8 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
First Contentful Paint 0.7 s
First Contentful Paint marks the time at which the first text or image is painted
Avoid chaining critical requests 7 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
Avoids an excessive DOM size 531 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 Meaningful Paint 0.9 s
First Meaningful Paint measures when the primary content of a page is visible
Keep request counts low and transfer sizes small 79 requests • 2,035 KB
To set budgets for the quantity and size of page resources, add a budget.json file
Serve static assets with an efficient cache policy 37 resources found
A long cache lifetime can speed up repeat visits to your page
Max Potential First Input Delay 350 ms
The maximum potential First Input Delay that your users could experience is the duration, in milliseconds, of the longest task
Time to Interactive 2.8 s
Time to interactive is the amount of time it takes for the page to become fully interactive
Links do not have descriptive text 1 link found
Descriptive link text helps search engines understand your content
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
Page load is not fast enough on mobile networks Interactive on simulated mobile network at 14.8 s
A fast page load over a cellular network ensures a good mobile user experience
Estimated Input Latency 110 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
Serve images in next-gen formats Potential savings of 485 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
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
Reduce server response times (TTFB) Root document took 630 ms
Time To First Byte identifies the time at which your server sends a response
Eliminate render-blocking resources Potential savings of 40 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
Efficiently encode images Potential savings of 12 KB
Optimized images load faster and consume less cellular data
Reduce the impact of third-party code Third-party code blocked the main thread for 340 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
Total Blocking Time 370 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
JavaScript execution time 1.1 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
Defer offscreen images Potential savings of 778 KB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive
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
Properly size images Potential savings of 581 KB
Serve images that are appropriately-sized to save cellular data and improve load time
Speed Index 1.6 s
Speed Index shows how quickly the contents of a page are visibly populated
First CPU Idle 2.2 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).
Avoids enormous network payloads Total size was 2,035 KB
Large network payloads cost users real money and are highly correlated with long load times

Mobile

Mobile Screenshot
Page load is not fast enough on mobile networks Interactive at 15.0 s
A fast page load over a cellular network ensures a good mobile user experience
First Contentful Paint (3G) 5025 ms
First Contentful Paint 3G marks the time at which the first text or image is painted while on a 3G network
Estimated Input Latency 1,200 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
Tap targets are sized appropriately 100% 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
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
Serve images in next-gen formats Potential savings of 591 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
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
Server response times are low (TTFB) Root document took 360 ms
Time To First Byte identifies the time at which your server sends a response
Eliminate render-blocking resources Potential savings of 0 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
Efficiently encode images Potential savings of 35 KB
Optimized images load faster and consume less cellular data
Reduce the impact of third-party code Third-party code blocked the main thread for 2,820 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
Total Blocking Time 4,240 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
