I have 2 boxes side by side both have gigabit ethernet connected to a
switch on the desk. The source is an i3-550 with /home mounted from an
md0-array of 4*1TB drives in a raid5 config and the sink is an E2200
with /home on 1 disk and an nfs mount point
issue command mv Fedora-18-x64.iso from source sink. The transfer
starts at 350Mb/s for about 200MB then drops to 500kb/s for the rest.
