Woocommerce section on front-end is very slow

Hi all!

We just installed a new WordPress website for our webshop with everything updates (WordPress, theme, plugins) and a new database. The PhP version is also updated to the latest version (which seems to make WordPress websites a little bit faster).The website is also optimized with some caching plugins.

The loading time of the homepage and subpages is about 2,5 seconds.

The only thing is: when you get to the woocommerce section on the website (like when you press ”Order” at productpage or when you press ”proceed to checkout” at cart), the loading takes very long, about 9,5 seconds. As far as I know we don’t load big data or anything (we have 6 SKU’s).

Does anyone know how this can be fixed or how I can find out what the cause is?

Thanks in advance!
