Need advice on improving filtering page performance NEXT

Hey everyone,

I’m currently working on a non-profit platform for dogs from shelters: https://hledaczvirat.cz/zvirata/psi/kontrakt-utulek.

The website helps people find animals for adoption fast and easily.
The main issue I’m fighting now is performance on filtering pages. If you examine the web vitals.

When users filter by breed, region, age, etc., the page sometimes gets slow to load and LCP/CLS scores drop hard.
I’m trying to make it faster for both users and Googlebot, but without breaking the UX.

Here’s what we’ve already tried:

• Cache layer (Redis) for API responses (still testing)
• Reduced image sizes and added lazy loading

But I still feel the Core Web Vitals could be much better, especially on mobile.

So I’m looking for your advice.

Thanks in advance
