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.
