Desktop

Desktop Screenshot
Total Blocking Time 140 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 270 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
Time to Interactive 1.5 s
Time to interactive is the amount of time it takes for the page to become fully interactive
First CPU Idle 1.4 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/).
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
Properly size images Potential savings of 22 KiB
Serve images that are appropriately-sized to save cellular data and improve load time
Avoids enormous network payloads Total size was 836 KiB
Large network payloads cost users real money and are highly correlated with long load times
Serve static assets with an efficient cache policy 13 resources found
A long cache lifetime can speed up repeat visits to your page
Largest Contentful Paint element 1 element found
This is the largest contentful element painted within the viewport
Avoid long main-thread tasks 4 long tasks found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay
Minimizes main-thread work 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 16 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive
Avoids an excessive DOM size 507 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 JavaScript Potential savings of 50 KiB
Remove unused JavaScript to reduce bytes consumed by network activity
Avoid large layout shifts 5 elements found
These DOM elements contribute most to the CLS of the page.
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
Cumulative Layout Shift 0.21
Cumulative Layout Shift measures the movement of visible elements within the viewport
First Contentful Paint 0.5 s
First Contentful Paint marks the time at which the first text or image is painted
Speed Index 0.7 s
Speed Index shows how quickly the contents of a page are visibly populated
Efficiently encode images Potential savings of 48 KiB
Optimized images load faster and consume less cellular data
Largest Contentful Paint 1.3 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Serve images in next-gen formats Potential savings of 109 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
Minimize third-party usage Third-party code blocked the main thread for 160 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
Initial server response time was short Root document took 150 ms
Keep the server response time for the main document short because all other requests depend on it
Remove unused CSS Potential savings of 44 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
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
JavaScript execution time 0.7 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
Keep request counts low and transfer sizes small 39 requests • 836 KiB
To set budgets for the quantity and size of page resources, add a budget.json file
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
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
First Meaningful Paint 0.5 s
First Meaningful Paint measures when the primary content of a page is visible

Defer offscreen images Potential savings of 21 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive
Max Potential First Input Delay 1,270 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
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
First Contentful Paint (3G) 3825 ms
First Contentful Paint 3G marks the time at which the first text or image is painted while on a 3G network
Avoids an excessive DOM size 486 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)

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
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 7.1 s
Time to interactive is the amount of time it takes for the page to become fully interactive
Serve static assets with an efficient cache policy 4 resources found
A long cache lifetime can speed up repeat visits to your page
