I can get anywhere between 4 and 11Mb/s on my 100Mb/s router. As others
have pointed out, scp is slow. At work, we use dd for rough estimates
of throughput. There are other limiting factors, too: the speed of the
slowest link, the inability of the kernel or NIC driver (or both) to
saturate bandwidth, window scaling, the MTU, and more.
