RTT in the context of the FortiGuard server list indicates the time it takes for a request to be sent to a FortiGuard server and for a response to be received.
This metric helps determine the latency between the FortiGate device and the FortiGuard servers, which is crucial for ensuring efficient and quick updates and responses for services like web filtering and antivirus updates.
Server Selection:
The FortiGate device uses RTT values to prioritize servers. Servers with lower RTT values are preferred as they respond faster, ensuring minimal delay in processing requests.
This improves the overall performance of FortiGuard services by reducing the time it takes to communicate with the servers.
