After this feature is enabled, it will detect the node network latency in real time and use the smart algorithm to select the optimal transfer path, so as to handle both static and dynamic client requests more quickly, stably, and securely. Smart dynamic routing minimizes problems such as high network latency, connection errors, and request failures.
