Improving GUI and CLI responsiveness (dedicated management CPU)

The GUI and CLI of FortiGate units with NP7, NP7Lite, NP6, or NP6XLite (SOC4) processors may become unresponsive when the system is under heavy processing load. This can occur if NP processor interrupts overload the CPU, preventing CPU cycles from being used for management tasks. You can improve GUI and CLI responsiveness by using the following command to dedicate CPU core 0 to management tasks.

config system npu

set dedicated-management-cpu enable

end

All management tasks are then processed by CPU 0. NP processor interrupts that would normally be handed by CPU 0 are added to CPU 1, resulting in CPU 1 processes more interrupts. The dedicated-management-cpu option is disabled by default.
