As iperf and other network protocols were confirmed to be fast by the OP it is very unlikely that it is a straight network problem. Yes, these effects do exist occasionally (weird interactions of higher level protocols and the low level stuff), but it is very rare. The cable that is so specifically broken to slow down NFS but not scp might exist, but it is very unlikely. /ralph
