Currently I'm running the Fortigate Firewall 90D as internet gateway, it's covering about 25 users to internet. I have a concern regarding the CPU usage. There is 99% utilization. I used the command "diag sys top" and I got the result as below. The process "src-vis" using almost 48,2%. I have tried to disable the disk log setting. But it still high. Do you have any ideas?
