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.
