cart Ajax cart: after adding 150 models, for add a new model (product) in cart takes 5-8 seconds

[Fior Di Loto]

Hello everyone,

I tried also in default demo prestashop https://demo.prestashop.com/#/en/front after adding all the products (present in the shop) in the cart, it starts to takes 1 second to cart.

my store use the same address to add the product:

https://www.ingrossoborseonline.com/en/cart

payload: token=bea08fe764c68f00006704d68eb4e1dd&id_product=6915&id_customization=0&group%5B2%5D=26&qty=1&add=1&action=update

time (after 150 models added in cart): 5.49 seconds

demo store after added all the products present in that store:

https://probable-look.demo.prestashop.com/en/cart

payload: token=5b2196eed6915b6edb57327708e63eb8&id_product=3&id_customization=0&group%5B3%5D=19&qty=1&add=1&action=update

time: 1.02 seconds

Why i am saying these things?

Is there a fix for that please?
