Technical Analysis

Opportunities

Enable text compression

• Description: Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more about text compression.
• Potential Savings: 900 ms

Remove duplicate modules in JavaScript bundles

• Description: Remove large, duplicate JavaScript modules from bundles to reduce unnecessary bytes consumed by network activity.

Avoid multiple page redirects

• Description: Redirects introduce additional delays before the page can be loaded. Learn how to avoid page redirects.

Reduce unused JavaScript

• Description: Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity. Learn how to reduce unused JavaScript.
• Potential Savings: 150 ms

Minify CSS

• Description: Minifying CSS files can reduce network payload sizes. Learn how to minify CSS.

Properly size images

• Description: Serve images that are appropriately-sized to save cellular data and improve load time. Learn how to size images.

Efficiently encode images

• Description: Optimized images load faster and consume less cellular data. Learn how to efficiently encode images.
• Potential Savings: Potential savings of 8 KiB

Preconnect to required origins

• Description: Consider adding preconnect or dns-prefetch resource hints to establish early connections to important third-party origins. Learn how to preconnect to required origins.

Eliminate render-blocking resources

• Description: 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.
• Potential Savings: 1510 ms

Avoid serving legacy JavaScript to modern browsers

• Description: 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 serve modern JavaScript

Use video formats for animated content

• Description: 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

Minify JavaScript

• Description: Minifying JavaScript files can reduce payload sizes and script parse time. Learn how to minify JavaScript.
• Potential Savings: Potential savings of 127 KiB

Reduce unused CSS

• Description: 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.
• Potential Savings: 750 ms

Preload Largest Contentful Paint image

• Description: If the LCP element is dynamically added to the page, you should preload the image in order to improve LCP. Learn more about preloading LCP elements.

Initial server response time was short

• Description: Keep the server response time for the main document short because all other requests depend on it. Learn more about the Time to First Byte metric.
• Potential Savings: 89 ms

Serve images in next-gen formats

• Description: 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.
• Potential Savings: 300 ms

Defer offscreen images

• Description: 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.

Diagnostics

Tasks

• Description: Lists the toplevel main thread tasks that executed during page load.

Avoid chaining critical requests

• Description: 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. Learn how to avoid chaining critical requests.
• Display Value: 8 chains found

Resources Summary

• Description: Aggregates all network requests and groups them by type

Network Requests

• Description: Lists the network requests that were made during page load.

Detected JavaScript libraries

• Description: All front-end JavaScript libraries detected on the page. Learn more about this JavaScript library detection diagnostic audit.

Server Backend Latencies

• Description: 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. Learn more about server response time.
• Display Value: 170 ms
• Numeric Value: 167

Final Screenshot

• Description: The last screenshot captured of the pageload.

Use a strong HSTS policy

• Description: Deployment of the HSTS header significantly reduces the risk of downgrading HTTP connections and eavesdropping attacks. A rollout in stages, starting with a low max-age is recommended. Learn more about using a strong HSTS policy.

Ensure proper origin isolation with COOP

• Description: The Cross-Origin-Opener-Policy (COOP) can be used to isolate the top-level window from other documents such as pop-ups. Learn more about deploying the COOP header.

Document has a main landmark.

• Description: One main landmark helps screen reader users navigate a web page. Learn more about landmarks.

Metrics

• Description: Collects all available metrics.
• Numeric Value: 3484

Network Round Trip Times

• Description: 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. Learn more about the Round Trip Time.
