Keep request counts low and transfer sizes small 32 requests • 902 KiB
To set budgets for the quantity and size of page resources, add a budget.json file
Use video formats for animated content Potential savings of 318 KiB
Large GIFs are inefficient for delivering animated content. Consider using MPEG4/WebM videos for animations and PNG/WebP for static images instead of GIF to save network bytes
Avoids an excessive DOM size 164 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)
Largest Contentful Paint 0.8 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Serve static assets with an efficient cache policy 25 resources found
A long cache lifetime can speed up repeat visits to your page
Time to Interactive 0.5 s
Time to interactive is the amount of time it takes for the page to become fully interactive
Cumulative Layout Shift 0.004
Cumulative Layout Shift measures the movement of visible elements within the viewport
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
Properly size images Potential savings of 9 KiB
Serve images that are appropriately-sized to save cellular data and improve load time
Avoid large layout shifts 2 elements found
These DOM elements contribute most to the CLS of the page.
Max Potential First Input Delay 20 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
Serve images in next-gen formats Potential savings of 180 KiB
Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption
First Contentful Paint 0.5 s
First Contentful Paint marks the time at which the first text or image is painted
Avoids enormous network payloads Total size was 902 KiB
Large network payloads cost users real money and are highly correlated with long load times
Minimizes main-thread work 0.1 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
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
Avoid chaining critical requests 6 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
Initial server response time was short Root document took 370 ms
Keep the server response time for the main document short because all other requests depend on it
First Meaningful Paint 0.5 s
First Meaningful Paint measures when the primary content of a page is visible
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
JavaScript execution time 0.0 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
Largest Contentful Paint element 1 element found
This is the largest contentful element painted within the viewport
Speed Index 1.1 s
Speed Index shows how quickly the contents of a page are visibly populated
Minify JavaScript Potential savings of 2 KiB
Minifying JavaScript files can reduce payload sizes and script parse time
Total Blocking Time 0 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
Eliminate render-blocking resources Potential savings of 280 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
