Please keep in mind that SCP has the overhead of encryption. All the
data is encrypted before being sent, and then decrypted at the other
end. So SCP will never be as fast as RCP, HTTP or FTP for file
transfers. I'm not a networking expect, so I won't try to guess how
much performance is lost using SCP. Perhaps someone else who is more
knowledgeable might answer that.
