Observer's Performance Suggestions
Priority actions Observer identified from this test to improve speed, reliability, and user experience.
2 images served larger than displayed
Error
Medium 2 images are served at intrinsic dimensions more than 120% of their display size. Worst offender is 157% of display size. Resize images to match their rendered dimensions to save bandwidth. Read more |
Slow Speed Index (6.3 s)
Warning
High The page takes too long to visually complete. Optimize critical rendering path, reduce render-blocking resources, and serve visible content first. Read more |
1 resource returned errors
Warning
High Sub-resources returned 4xx or 5xx status codes. Broken scripts, stylesheets, or images can degrade functionality and user experience. Read more |
Domain transfer lock is not enabled
Warning
Medium The domain has neither clientTransferProhibited nor serverTransferProhibited status, which means it could be transferred to another registrar without additional safeguards. Enable transfer lock through your registrar to prevent unauthorized transfers. Read more |
Desktop performance needs improvement (72/100)
Warning
Medium Score is below 90. Tackle the highest-impact audits to push into the green. Read more |
Mobile performance needs improvement (58/100)
Warning
Medium Score is below 90. Tackle the highest-impact audits to push into the green. Read more |
Heavy page weight (6.1 MB)
Warning
Medium Total transfer exceeds 5 MB. Trim images, scripts, and fonts to reduce data costs and load time. Read more |
10 render-blocking resources
Warning
Medium More than 3 resources block initial rendering. Defer or async non-critical scripts and inline critical CSS to speed up first paint. Read more |
32 resources served over HTTP/1.1
Warning
Medium HTTP/1.1 lacks multiplexing, causing head-of-line blocking. Upgrade to HTTP/2 or HTTP/3 for better parallelism and reduced latency. Read more |
18 text resources not compressed
Warning
Medium Text-based assets (JS, CSS, JSON, SVG) are served without gzip or Brotli compression, wasting bandwidth. Enable compression on your server or CDN. Read more |

|---|---|---|
| Time to Interactive | 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. | 25.0 s |
| Largest Contentful Paint | Largest Contentful Paint marks the time at which the largest text or image is painted. Learn more about the Largest Contentful Paint metric | 24.4 s |
| 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
| Est savings of 686 KiB |
| Reduce unused CSS | 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.
| Est savings of 284 KiB |
| Minify JavaScript | Minifying JavaScript files can reduce payload sizes and script parse time. Learn how to minify JavaScript.
| Est savings of 357 KiB |
| Reduce unused JavaScript | Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity. Learn how to reduce unused JavaScript.
| Est savings of 695 KiB |
| Font display | Consider setting font-display to swap or optional to ensure text is consistently visible. swap can be further optimized to mitigate layout shifts with font metric overrides.
| Est savings of 150 ms |
