Heavy LCP image load delay despite fetchpriority and eager loading

Heavy LCP image load delay despite fetchpriority and eager loading

Hi there,

although the lcp image is loaded "eager" and fetchpriority is "high" we have a load delay of 10,190 ms. Also render delay is quite high with 1,650ms despite the fact that the image is responsive (800px width for mobile).

Any ideas how to improve?

Cheers

Convert your banner images from jpeg to webp and compress them. It will improve the performance.

Shopif does serve automatically in webP...

This is how the images are rendered:

  {{ type | image_url: width: width | default: 1200 | image_tag:
    loading: loading,
    fetchpriority: fetchpriority,
    sizes: sizes,
    alt: alt,
    widths: '200, 300, 400, 500, 600, 700, 800, 1000, 1200, 1400, 1600, 1800, 2000, 2200, 2400, 2600, 2800, 3000'
  }}
