Hzyunxitech.com Test Results

Hzyunxitech.com Mobile Performance: 66/100
Quick overview:
LCP request discovery
Optimize LCP by making the LCP image discoverable from the HTML immediately, and avoiding lazy-loading
Render blocking requests
Est savings of 920 ms
Requests are blocking the page's initial render, which may delay LCP. Deferring or inlining can move these network requests out of the critical path.
Use efficient cache lifetimes
Est savings of 7,582 KiB
A long cache lifetime can speed up repeat visits to your page. Learn more.
Network dependency tree
Avoid chaining critical requests by reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load.
Improve image delivery
Est savings of 7,280 KiB
Reducing the download time of images can improve the perceived load time of the page and LCP. Learn more about optimizing image size
Forced reflow
A forced reflow occurs when JavaScript queries geometric properties (such as offsetWidth) after styles have been invalidated by a change to the DOM state. This can result in poor performance. Learn more about forced reflows and possible mitigations.
Time to Interactive
7.8 s
Time to Interactive is the amount of time it takes for the page to become fully interactive. Learn more about the Time to Interactive metric.
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Reduce unused JavaScript
Est savings of 31 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.
Avoid an excessive DOM size
896 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows. Learn how to avoid an excessive DOM size.
Largest Contentful Paint element
7,810 ms
This is the largest contentful element painted within the viewport. Learn more about the Largest Contentful Paint element
Properly size images
Est savings of 4,520 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn how to size images.
Minify JavaScript
Est savings of 8 KiB
Minifying JavaScript files can reduce payload sizes and script parse time. Learn how to minify JavaScript.
Eliminate render-blocking resources
Est savings of 1,010 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.
Avoid multiple page redirects
Est savings of 2,010 ms
Redirects introduce additional delays before the page can be loaded. Learn how to avoid page redirects.
Image elements do not have explicit `width` and `height`
Set an explicit width and height on image elements to reduce layout shifts and improve CLS. Learn how to set image dimensions
Serve static assets with an efficient cache policy
109 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more about efficient cache policies.
Avoid enormous network payloads
Total size was 7,618 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn how to reduce payload sizes.
