Performance of the main product photo gallery (PageSpeed mobile)
-
I noticed that the main product gallery in the theme actually creates problems for LCP on mobile devices according to PageSpeed Insights reports.
Because of this, the yellow zone 50-60 is constantly on mobile.
This is visible even on the demo site.

Additionally, I posted this as a suggestion: https://woodmart.canny.io/feature-requests/p/optimizing-the-performance-of-the-main-product-photo-gallery-pagespeed-mobile
At the same time, there are no problems on the desktop – the indicators are in the green zone.
PS. Detected before theme version 8.2 was released
Hello,
On the demo website, there is such an issue because the image has weight due to high quality, which is why that issue shows there. In order to solve the LCP problem there needs to reduce the weight of the image, but for the demo, it is important for us that the pictures have high quality.
We are oriented to this https://monosnap.com/file/EIOYomGjONHBX8CKqAxE0at7K4cSwC test, which is working for the real customers and as you can see, there is the LCP is in the green zone.
In the future, we will investigate the best way to optimize it as best as possible.
Kind Regards
I’m not sure if the problem is the size of the uploaded image. Because the main LCP delay is due to Element Render Delay. I see a similar situation not only on the demo site, but also on others (there the weight of the images is less than 50 kilobytes).
It seems to me that on the product page there is a mismatch in the priority of script execution, which affects the rendering.
I hope in the future you will consider optimizing the performance of the gallery on the product page. Thank you!
