FortiMail Troubleshooting: Slow Performance

Problem: Slow Performance

The FortiMail unit is suffering from slow or stalled performance.

The Solution

Use the CLI to view a list of the most system-intensive processes. From the CLI you will be able to see what processes are using the most resources. For example: 
diagnose system top 10
The above command generates a report of processes every ten seconds. The report provides the process names, their process ID (pid), status, CPU usage, and memory usage. 

The report continues to refresh and display in the CLI window until you enter q (quit).
