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.

Preconnect to required origins
Consider adding `preconnect` or `dns-prefetch` resource hints to establish early connections to important third-party origins. Learn more.

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. Learn more.

Avoid chaining critical requests - 10 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. Learn more.

Preload key requests
Consider using `` to prioritize fetching resources that are currently requested later in page load. Learn more.

Minify JavaScript
Minifying JavaScript files can reduce payload sizes and script parse time. Learn more.

User Timing marks and measures
Consider instrumenting your app with the User Timing API to measure your app's real-world performance during key user experiences. Learn more.

Use video formats for animated content
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.

Server response times are low (TTFB) - Root document took 20 ms
Time To First Byte identifies the time at which your server sends a response. Learn more.

Enable text compression
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more.

Eliminate render-blocking JavaScript and CSS in above-the-fold content

Your page has 5 blocking CSS resources. This causes a delay in rendering your page.

None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.Optimize CSS Delivery of the following:

https://selenium.dev/css/header.css
https://selenium.dev/css/main.css
https://selenium.dev/css/index.css
https://fonts.googleapis.com/css?family=Encode+Sans+Condensed:400,700
https://fonts.googleapis.com/css?family=Encode+Sans:300,700

Leverage browser caching

Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.

Leverage browser caching for the following cacheable resources:

https://selenium.dev/css/footer.css (10 minutes)
https://selenium.dev/css/header.css (10 minutes)
https://selenium.dev/css/index.css (10 minutes)
https://selenium.dev/css/main.css (10 minutes)
https://selenium.dev/images/facebook.png (10 minutes)
https://selenium.dev/images/github.png (10 minutes)
https://selenium.dev/images/green-bg-opt.jpg (10 minutes)
