Image shows a grid of four columns and eight rows detailing the difference between four common types of file transfer: tftp, ftp, sftp, and scp; across eight data points: transfer protocol, standard port, speed overview, security overview, authentication support, encryption support, and connection orientation.

  • TFTP : UDP, port 69, Fast, Less Secure, No Authentication, No Encryption, and Connection-less
  • FTP: TCP, port 20, 21, Slow, Less Secure, Authentication, No Encryption, and Connection-oriented
  • SFTP: TCP, Port 22, Slow, Secure, Authentication, Encryption, and Connection-oriented
  • SCP: TCP, Port 22, Fast, Secure, Authentication, Encryption, and Connection-oriented

    I don’t understand (in this day and age) how any of these protocols have comparable performance difference to need the “Fast”/“Slow” row. None of these protocols would be computationally intensive enough to make a difference in performance, and should be only limited by line speed, no?
