Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Reduce the impact of third-party code
Third-party code blocked the main thread for 890 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. Learn how to minimize third-party impact.
Reduce JavaScript execution time
1.4 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this. Learn how to reduce Javascript execution time.
Largest Contentful Paint image was lazily loaded
Above-the-fold images that are lazily loaded render later in the page lifecycle, which can delay the largest contentful paint. Learn more about optimal lazy loading.
Properly size images
Potential savings of 752 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn how to size images.
Largest Contentful Paint element
9,660 ms
This is the largest contentful element painted within the viewport. Learn more about the Largest Contentful Paint element
Serve images in next-gen formats
Potential savings of 40 KiB
Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption. Learn more about modern image formats.
Avoid multiple page redirects
Potential savings of 1,110 ms
Redirects introduce additional delays before the page can be loaded. Learn how to avoid page redirects.
Minimize main-thread work
2.3 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this. Learn how to minimize main-thread work
Reduce unused CSS
Potential savings of 61 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity. Learn how to reduce unused CSS.
Minify CSS
Potential savings of 12 KiB
Minifying CSS files can reduce network payload sizes. Learn how to minify CSS.
Use video formats for animated content
Potential savings of 308 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
Eliminate render-blocking resources
Potential savings of 3,430 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles. Learn how to eliminate render-blocking resources.
Serve static assets with an efficient cache policy
5 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more about efficient cache policies.
Minify JavaScript
Potential savings of 40 KiB
Minifying JavaScript files can reduce payload sizes and script parse time. Learn how to minify JavaScript.
Avoid serving legacy JavaScript to modern browsers
Potential savings of 8 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. Learn how to use modern JavaScript
Reduce unused JavaScript
Potential savings of 61 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity. Learn how to reduce unused JavaScript.
