Reserve.489ban.net Test Results

Reserve.489ban.net Mobile Performance: 47/100
Quick overview:
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Avoid an excessive DOM size
1,034 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.
Minimize main-thread work
2.4 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this. Learn how to minimize main-thread work
Reduce the impact of third-party code
Third-party code blocked the main thread for 320 ms
Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading. Learn how to minimize third-party impact.
Defer offscreen images
Potential savings of 2,203 KiB
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.
Reduce unused JavaScript
Potential savings of 291 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 multiple page redirects
Potential savings of 1,110 ms
Redirects introduce additional delays before the page can be loaded. Learn how to avoid page redirects.
Serve images in next-gen formats
Potential savings of 1,594 KiB
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.
Enable text compression
Potential savings of 415 KiB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more about text compression.
Eliminate render-blocking resources
Potential savings of 2,010 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.
Largest Contentful Paint element
14,600 ms
This is the largest contentful element painted within the viewport. Learn more about the Largest Contentful Paint element
Reduce unused CSS
Potential savings of 153 KiB
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.
Minify CSS
Potential savings of 17 KiB
Minifying CSS files can reduce network payload sizes. Learn how to minify CSS.
Properly size images
Potential savings of 1,158 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn how to size images.
Avoid serving legacy JavaScript to modern browsers
Potential savings of 10 KiB
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
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 about adopting passive event listeners.
Preload Largest Contentful Paint image
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.
Avoid enormous network payloads
Total size was 4,158 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn how to reduce payload sizes.
Serve static assets with an efficient cache policy
31 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more about efficient cache policies.
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
Efficiently encode images
Potential savings of 32 KiB
Optimized images load faster and consume less cellular data. Learn how to efficiently encode images.
Minify JavaScript
Potential savings of 4 KiB
Minifying JavaScript files can reduce payload sizes and script parse time. Learn how to minify JavaScript.
Insights
Render blocking requests
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.
Improve image delivery
Reducing the download time of images can improve the perceived load time of the page and LCP. Learn more about optimizing image size
Layout shift culprits
Layout shifts occur when elements move absent any user interaction. Investigate the causes of layout shifts, such as elements being added, removed, or their fonts changing as the page loads.
Optimize viewport for mobile
Tap interactions may be delayed by up to 300 ms if the viewport is not optimized for mobile.
LCP request discovery
Optimize LCP by making the LCP image discoverable from the HTML immediately, and avoiding lazy-loading
Third parties
Third party code can significantly impact load performance. Reduce and defer loading of third party code to prioritize your page's content.
Document request latency
Your first network request is the most important. Reduce its latency by avoiding redirects, ensuring a fast server response, and enabling text compression.
Time to Interactive
19.1 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.
Max Potential First Input Delay
280 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task. Learn more about the Maximum Potential First Input Delay metric.

Quick overview:
General
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 about this errors in console diagnostic audit
Trust and Safety
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 served over 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 about HTTPS.
Reserve.489ban.net Mobile Accessibility: 88/100
Quick overview:
Best practices
These items highlight common accessibility best practices.
Touch targets do not have sufficient size or spacing.
Touch targets with sufficient size and spacing help users who may have difficulty targeting small controls to activate the targets. Learn more about touch targets.
Names and labels
These are opportunities to improve the semantics of the controls in your application. This may enhance the experience for users of assistive technology, like a screen reader.
Links do not have a discernible name
Link text (and alternate text for images, when used as links) that is discernible, unique, and focusable improves the navigation experience for screen reader users. Learn how to make links accessible.
Contrast
These are opportunities to improve the legibility of your content.
Background and foreground colors do not have a sufficient contrast ratio.
Low-contrast text is difficult or impossible for many users to read. Learn how to provide sufficient color contrast.
