No particular impact, especially for file transfer. The pub/priv keys are 
only used for authentication and a symmetric key is used for encrypting 
traffic during the session. I use a 2048-bit RSA key routinely - if it's 
any slower than a 1048-bit key during the authentication phase, it's not 
noticeable, and it has no impact on file transfer.
