I am having problems accessing pages, these pages do not load well or sometimes take a long time to load.
I make a test policy, without enabling security filters and it still does not load. Verify that the device is using Fortiguard DNS and that those DNS are experiencing latency (you do not have the ISP provider's DNS)
Could that contribute to the page not loading correctly or taking a while to load?
Since we do not have the ISP's DNS, we use fortiguard's DNS
If the DNS servers you're using are slow to respond, it can delay the time it takes for your browser to resolve the domain name to an IP address, which is the first step in loading a web page. Use tools like ping or nslookup to check the response time from the FortiGuard DNS servers. High latency or packet loss could indicate a problem. Sometimes, the issue might not be DNS-specific but a general internet connectivity issue. Run a speed test to check your bandwidth and latency. For testing purposes, you can temporarily switch to a different DNS service like Google's (184.108.40.206 and 220.127.116.11) to see if the issue persists. If you find that the FortiGuard DNS servers are slow, consider switching to another DNS service.
