Desktop Screenshot
Avoids enormous network payloads Total size was 772 KiB
Large network payloads cost users real money and are highly correlated with long load times
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
Avoids an excessive DOM size 357 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)
Reduce unused JavaScript Potential savings of 175 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity
First Contentful Paint 0.7 s
First Contentful Paint marks the time at which the first text or image is painted
Time to Interactive 1.6 s
Time to interactive is the amount of time it takes for the page to become fully interactive
JavaScript execution time 0.4 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 540 ms
Keep the server response time for the main document short because all other requests depend on it
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
Speed Index 1.0 s
Speed Index shows how quickly the contents of a page are visibly populated
Largest Contentful Paint element 1 element found
This is the largest contentful element painted within the viewport
Avoid serving legacy JavaScript to modern browsers Potential savings of 14 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
Uses efficient cache policy on static assets 2 resources found
A long cache lifetime can speed up repeat visits to your page
Max Potential First Input Delay 150 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
Cumulative Layout Shift 0.001
Cumulative Layout Shift measures the movement of visible elements within the viewport
Avoid large layout shifts 3 elements found
These DOM elements contribute most to the CLS of the page.
Eliminate render-blocking resources Potential savings of 440 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles

To set budgets for the quantity and size of page resources, add a budget.json file
Web app manifest or service worker do not meet the installability requirements 1 reason
Service worker is the technology that enables your app to use many Progressive Web App features, such as offline, add to homescreen, and push notifications. With proper service worker and manifest implementations, browsers can proactively prompt users to add your app to their homescreen, which can lead to higher engagement
Total Blocking Time 110 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
Avoid chaining critical requests 19 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

Preload key requests Potential savings of 1,050 ms
Consider using `<link rel=preload>` to prioritize fetching resources that are currently requested later in page load
Document uses legible font sizes 99.58% 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
Max Potential First Input Delay 160 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
Time to Interactive 9.2 s
Time to interactive is the amount of time it takes for the page to become fully interactive
