Your expectations are to high. If you have about 20%
utilisation with a
Gbit nic, I'd say you are doing verry nice.
With the move to gigabit networking, the nic is no longer
the
bottleneck. If you move data from disk on one machine or to
disk on an
other, the disk-controllers, disk interfaces or even the
actual disks
are most likely the bottlenecks. Then, the disk does not
need to be the
bottleneck. Think about the speed of internal busses and for
which they
are used while you are dumping data...
