During FXP transmission, the file is not downloaded to the local computer. The local computer only sends control commands. Therefore, the speed of FXP transmission is only related to the network speed between the two FTP servers and has nothing to do with the local speed.
Because the FXP method only sends commands locally, after starting the transmission, as long as the local computer does not send a stop command, even if the local computer is shut down, FXP is still transmitting until a file transmission is completed or a file transmission error occurs. When the FTP server waits for the local command to be sent, it will terminate the FXP transfer because it cannot receive the command.
Due to the above reasons, when an FXP transmission error occurs, the local user process remains in the FTP server and does not exit. If the FTP server is connected again at this time, the FTP server may prompt the client because the user thread exceeds the allowable limit. Logged in and rejects the client's connection, the server cannot connect to the FTP server again until the puppet process in the server is killed by the FTP server due to timeout or other reasons.
