My cart/checkout and “logged-in users area” is very slow

Hello,

i just recently changed my Hoster to a managed vServer.

I migrated with Migrate Guru and everything seems fine.

My site is loading really fast usually.

BUT there are a couple of areas where it is very very slow.

My Cart for example is very very slow, it takes 20-40 seconds until it loads. The same thing happens with checkout.

Also when someone is logged in, the site is also very slow.

But when you visit the same products without being logged in, it loads extremly fast.

Do you have any idea what is causing this.
As i told you, i just moved to another hoster. Before that, everything was fast.
The new package i booked is way better then the old one. So its definitely not the performance of the server.

Thank you in advance
