I am looking for a table comparison between SSH ciphers, as I do want to know if I can speed-up two things:

  • initial connection time, especially when using key authentication (rsa)
  • file transfer speed

Thanks, I am ware about this page but still, it doesn't say anything about initial connection time and security, these are still open-questions. – sorin Jan 9 '13 at 11:47
Ironically, this answer is now one of google's favorite links for answering the above question! – dmansfield Jun 8 '15 at 14:42

The speediest approach for file transfer is to disable encryption entirely. This is detailed in my answer at: Copying files between linux machines with strong authentication but without encryption

Short of that, I make use of the arcfour cipher.
