Page speed issues | WordPress.org

I’ve been struggling with slow loading times on my WordPress site. Recently, I noticed that after uploading an image in the hero section, my Core Web Vitals score decreased significantly. Despite trying various optimizations, the speed is still not where I want it to be. What plugins do you recommend for optimizing images and improving overall site speed? Has anyone else experienced similar issues with their WordPress site? What steps did you take to diagnose and fix the speed problems?
