We have deployed vm-series 300 in AWS recently and put our production site behind it, but we are seeing a performance degradation, the website is taking around 2-3 mins to load for the first time which normally it didnt take, we have not put any url filtering profiles yet but yes we do have some security and nat profiles in place(which normal I believe), I just wanted to understand what could be the reason for the slowness and what all things can be checked in PA to troubleshoot.
PS: I am attaching a screenshot of developers tool console to show time it takes for the page to load first time

How are you directing traffic to the firewalls? If you are using an ALB/NLB, ensure that your routing allows the firewalls to communicate with all of the LB Subnets via the same interface that is specified in the Target Group. Similar question on the backend. If the application is deployed across multiple subnets, ensure the firewall can route to all of the backend subnets via the SNAT interface.

Yes, we are using NLB, which is deployed in 2 subnets across 2 az's, the backed firewalls are also in the same AZ's. The backend to the firewall is an Haproxy which are also spread across the same az's.
