I haven't tried other protocols yet (FTP and HTTP) I'll check that tomorrow.
This is a pretty crucial test. It'll be difficult to diagnose the issue until you know whether the protocol is contributing to the problem or merely symptomatic of it.
Also, I assume that you're scp-ing files to and from local disk, not filesystems with network dependencies (nfs or cifs), right?
