  • First, you need to put Magento 2 in production mode to use Merged JS, and also try JS Bundling. Commented May 18, 2018 at 20:54

what you can try:

  1. CSS sprites to merge many images into one.
  2. inline small CSS/JS files right into HTML.
  3. use base64 data for small images https://css-tricks.com/data-uris/
  4. CDN or domain sharding https://www.maxcdn.com/one/visual-glossary/domain-sharding-2/
  5. enable HTTP2

You have to use lazy load functionality for homepage, It is presumed there are number of products you showing on homepage and all product images have separate request.

You have to go with this : http://www.appelsiini.net/projects/lazyload/enabled_gazillion.html

By this images will load on scroll and only one request fire for all catalog images.

Defiantly this will make sense in your requests.
