Remove unused JavaScript. Potential savings of 254 KiB
Remove unused JavaScript to reduce bytes consumed by network activity. Learn more.
Reduce initial server response time. Root document took 2,070 ms
Keep the server response time for the main document short because all other requests depend on it. Learn more.
Remove unused CSS. Potential savings of 134 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. Learn more.
Eliminate render-blocking resources. Potential savings of 1,080 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles. Learn more.
Defer offscreen images. Potential savings of 46 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive. Learn more.
Serve images in next-gen formats. Potential savings of 23 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. Learn more.
Preload key requests. 0 ms
Consider using `<link rel=preload>` to prioritize fetching resources that are currently requested later in page load. Learn more.
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
