Hi,
I have too many dom requests and I have such a problem.
I will be glad if you help.
“This is happening because of the theme, the theme is using a 600px image which Smush CDN will serve and apply the responsive images, but, the theme is also resizing the images using CSS to 65px.
I suggest contacting your theme provider to fix this problem, a good idea is to register an image size for that part of the home page and call it properly on the front end avoiding the resizes.”
