Hello @kkhebbar89
Thank you for your report.

We have rechecked this on Magento 2.4- develop with over 90 products in the Cart.
The processes take some time to accomplish, but not as much time as on the screenshots you've attached.
For example, the Sign In takes about 4 seconds, Cart Checkout, about 8 seconds, Adding to Cart, about 4 seconds.

Can you please confirm that you are experiencing the same performance on Magento 2.4-develop ?

Hello @engcom-Bravo
Checked the same in Magento 2.4- develop, there I see very good perfomance. Please find below the screeshots.

Are any changes done for enhancing perfomance in Magento 2.4.0. Can you please share the commit for the same.

Thanks & Regards,
Karthik S.

@kkhebbar89
Thank you for the response.
I tried to find a related task for it by keywords but unfortunately, with no result.
Probably it was done in scope on some bug fix or other task (internal or external)

So if the issue is not reproducible on 2.4-develop, we have to close this issue.
Thank you for your collaboration.

Calling load times in cart and checkout of around 8-10 seconds a "very good perfomance" is ludicrous.
