Super slow Woocommerce Web Shop

For months I’ve been trying to solve this problem. Using WP Rocket to cache, optimize images, clean up comments. All active plugins fit PHP7 and WordPress 4.7.2. Using Yoast for tracking XML-sitemap. Our hosting type Shared Web Hosting and according to the company that the hosting company this shouldn’t be a problem (they did not notice anything that could possibly affect the woocommerce page). Seriously, what can the problem be then?

This issue applies only to the Webshop that’s based on Woocommerce. We have the latest update. I’ve also noticed that it takes too long to upload the product backend page (in the admin page).

I’m totally lost here. How can this problem be solved?
