Hello,
1/ Please, disable ajax option on your Products element on the home page because there is no sence in enabling ajax loading option for the elements which are shown in the first client’s window.
2/ Please, use the navigation option or infinite loading because it will make your products to load not all at once but for example 12 and when customer will scroll down a bit (or click Load more button) then element will load 12 more. For now, you are loading about 60 products at once and each of them has a swap effect which requires 2 images to load for each product.
Kind Regards,
