ssh supports several ciphers.

 The ciphers used have a large impact on the performance. 

From faster ones to slower ones:

arcfour >> blowfish >> aes >> 3des

arcfour and blowfish have security problem.

It is also a good idea to enable compression by default so that ssh performs better over a low-bandwidth link, such as a slow Internet connection.

vim ~/.ssh/config:

Ciphers arcfour
Compression yes
