Does anyone have any hard data about the relative speeds file transfer technologies? I'm particularly interested in empirical data relating to wget vs rsync vs scp. This would be applied to an internal network, so latency isn't really an issue. The goal is to determine the best way to transfer largish tarballs (size varies, but is typically in the 10s of GBs) in the most efficient way in terms of both time and machine resources. At the moment we're using wget, and in my (anecdotal) experience wget performed at least as well as rsync, typically, at least in terms of speed, and probably better than rsync in terms of machine resources (that initial calculation of the job size, etc can be a little intense when you're moving 100-1000+ GB). My experience with scp in this sphere is more limited. I really only use it to transfer smallish groups of files of much less girth than the ones previously mentioned, so have never had to push enough through it to get a feel for speed or resources required.
