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.
Reduce initial server response time. Root document took 1,090 ms
Keep the server response time for the main document short because all other requests depend on it. Learn more.
Preload key requests. Potential savings of 600 ms
Consider using `<link rel=preload>` to prioritize fetching resources that are currently requested later in page load. Learn more.
Avoid multiple page redirects. Potential savings of 570 ms
Redirects introduce additional delays before the page can be loaded. Learn more.
Eliminate render-blocking resources. Potential savings of 120 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.
Remove unused JavaScript. Potential savings of 111 KiB
Remove unused JavaScript to reduce bytes consumed by network activity. Learn more.
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Ensure text remains visible during webfont load
Leverage the font-display CSS feature to ensure text is user-visible while webfonts are loading. Learn more.
Does not use passive listeners to improve scrolling performance
Consider marking your touch and wheel event listeners as `passive` to improve your page's scroll performance. Learn more.
Serve static assets with an efficient cache policy
34 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more.
Avoid enormous network payloads
Total size was 4,680 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn more.
Keep request counts low and transfer sizes small
60 requests • 4,680 KiB
To set budgets for the quantity and size of page resources, add a budget.json file. Learn more.
Avoid large layout shifts
5 elements found
These DOM elements contribute most to the CLS of the page.
Avoid chaining critical requests
17 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.
Avoid long main-thread tasks
2 long tasks found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay. Learn more

Does not use HTTPS
1 insecure request found
All sites should be protected with HTTPS, even ones that don't handle sensitive data. This includes avoiding mixed content, where some resources are loaded over HTTP despite the initial request being servedover HTTPS. HTTPS prevents intruders from tampering with or passively listening in on the communications between your app and your users, and is a prerequisite for HTTP/2 and many new web platform APIs. Learn more.
Includes front-end JavaScript libraries with known security vulnerabilities
4 vulnerabilities detected
Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers. Learn more.
General
Registers an `unload` listener
The `unload` event does not fire reliably and listening for it can prevent browser optimizations like the Back-Forward Cache. Consider using the `pagehide` or `visibilitychange` events instead. Learn More
Browser errors were logged to the console
Errors logged to the console indicate unresolved problems. They can come from network request failures and other browser concerns. Learn more
