Consider modifying your JavaScript build process to not transpile Baseline features, unless you know you must support legacy browsers. Learn why most sites can deploy ES6+ code without transpiling
Avoid enormous network payloads
Total size was 10,441 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn how to reduce payload sizes.
Defer offscreen images
Est savings of 2,454 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive. Learn how to defer offscreen images.
Use video formats for animated content
Est savings of 777 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. Learn more about efficient video formats
Properly size images
Est savings of 6,321 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn how to size images.
Minify JavaScript
Est savings of 3 KiB
Minifying JavaScript files can reduce payload sizes and script parse time. Learn how to minify JavaScript.
Optimize DOM size
A large DOM can increase the duration of style calculations and layout reflows, impacting page responsiveness. A large DOM will also increase memory usage. Learn how to avoid an excessive DOM size.
LCP request discovery
Optimize LCP by making the LCP image discoverable from the HTML immediately, and avoiding lazy-loading
Use efficient cache lifetimes
Est savings of 430 KiB
A long cache lifetime can speed up repeat visits to your page. Learn more.
Layout shift culprits
Layout shifts occur when elements move absent any user interaction. Investigate the causes of layout shifts, such as elements being added, removed, or their fonts changing as the page loads.
Network dependency tree
Avoid chaining critical requests by reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load.
Improve image delivery
Est savings of 4,615 KiB
Reducing the download time of images can improve the perceived load time of the page and LCP. Learn more about optimizing image size
Render blocking requests
Requests are blocking the page's initial render, which may delay LCP. Deferring or inlining can move these network requests out of the critical path.
Forced reflow
Many APIs, typically reading layout geometry, force the rendering engine to pause script execution in order to calculate the style and layout. Learn more about forced reflow and its mitigations.
Time to Interactive
19.5 s
Time to Interactive is the amount of time it takes for the page to become fully interactive. Learn more about the Time to Interactive metric.
Max Potential First Input Delay
390 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task. Learn more about the Maximum Potential First Input Delay metric.
Legacy JavaScript
Est savings of 30 KiB
Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. Consider modifying your JavaScript build process to not transpile Baseline features, unless you know you must support legacy browsers. Learn why most sites can deploy ES6+ code without transpiling
