Desktop
Time to Interactive
3.7 s
Time to interactive is the amount of time it takes for the page to become fully interactive
Total Blocking Time
0 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
Largest Contentful Paint element
1 element found
This is the largest contentful element painted within the viewport
Avoid multiple page redirects
Potential savings of 2,580 ms
Redirects introduce additional delays before the page can be loaded
Keep request counts low and transfer sizes small
49 requests • 2,792 KiB
To set budgets for the quantity and size of page resources, add a budget.json file
Remove unused JavaScript
Potential savings of 512 KiB
Remove unused JavaScript to reduce bytes consumed by network activity
Preload key requests
Potential savings of 2,140 ms
Consider using `<link rel=preload>` to prioritize fetching resources that are currently requested later in page load
First CPU Idle
3.7 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/).
First Contentful Paint
3.7 s
First Contentful Paint marks the time at which the first text or image is painted
Avoid large layout shifts
4 elements found
These DOM elements contribute most to the CLS of the page.
Page load is not fast enough on mobile networks
Interactive on simulated mobile network at 20.6 s
A fast page load over a cellular network ensures a good mobile user experience
Largest Contentful Paint
4.3 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Remove unused CSS
Potential savings of 526 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
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
Minify CSS
Potential savings of 31 KiB
Minifying CSS files can reduce network payload sizes
JavaScript execution time
0.9 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
Avoid serving legacy JavaScript to modern browsers
Potential savings of 5 KiB
Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. For your bundled JavaScript, adopt a modern script deployment strategy using module/nomodule feature detection to reduce the amount of code shipped to modern browsers, while retaining support for legacy browsers
User Timing marks and measures
52 user timings
Consider instrumenting your app with the User Timing API to measure your app's real-world performance during key user experiences
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
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
Eliminate render-blocking resources
Potential savings of 580 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
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
Avoid long main-thread tasks
3 long tasks found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay
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
Minimizes main-thread work
1.7 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
Cumulative Layout Shift
0.028
Cumulative Layout Shift measures the movement of visible elements within the viewport
Max Potential First Input Delay
30 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
Speed Index
3.7 s
Speed Index shows how quickly the contents of a page are visibly populated
Serve images in next-gen formats
Potential savings of 25 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
Properly size images
Potential savings of 27 KiB
Serve images that are appropriately-sized to save cellular data and improve load time
First Meaningful Paint
3.7 s
First Meaningful Paint measures when the primary content of a page is visible
Initial server response time was short
Root document took 90 ms
Keep the server response time for the main document short because all other requests depend on it
Serve static assets with an efficient cache policy
15 resources found
A long cache lifetime can speed up repeat visits to your page
Avoid enormous network payloads
Total size was 2,792 KiB
Large network payloads cost users real money and are highly correlated with long load times
Avoids an excessive DOM size
43 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)
robots.txt is not valid
57 errors found
If your robots.txt file is malformed, crawlers may not be able to understand how you want your website to be crawled or indexed

Speed Index
18.4 s
Speed Index shows how quickly the contents of a page are visibly populated
Document doesn't use legible font sizes
47.19% 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
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
