Observer's Performance Suggestions

Priority actions Observer identified from this test to improve speed, reliability, and user experience.

13 images served larger than displayed

Error Medium

13 images are served at intrinsic dimensions more than 120% of their display size. Worst offender is 447% of display size. Resize images to match their rendered dimensions to save bandwidth. Read more

Slow Speed Index (19.4 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

LCP image TTFB is slow

Warning High

The p75 LCP image time-to-first-byte is 1431 ms. Use a faster origin server, CDN, or preconnect hints to reduce initial response time. Read more

Desktop performance needs improvement (57/100)

Warning Medium

Score is below 90. Tackle the highest-impact audits to push into the green. Read more

Slow Speed Index (3.8 s)
