The most efficient, if security isn't a concern, would be to use FTP. The next best choice I'd think would be NFS.

I agree with jim. However you can have security & efficiency by using sftp.

Does sftp use a sliding window for data packets and acks? I was thinking that it didn't and could not get the transfer rates that FTP can.

i was hoping for something that was optimized for large files. I looked at bbftp but not sure if that is the way to go

That looks like it might be a good choice.

Hi,

I don't think you will get (much) better performance with ftp vs scp. (have you tested?)

I can't recommend NFS for this, it is slow and has some issues depending on wich version you are running. (NFSv2 has a 2GB file limit...)

Stick with scp and upgrade the network if you want faster transfers, Gbit ethernet is very cheap!
