The linux 'netcat' utility can send anything you like, pretty much as fast as the NIC of the sending machine(s) can put it onto the wire.

From the docs (here http://nc110.sourceforge.net/):

"You can use netcat to generate huge amounts of useless network data for
various performance testing.  For example, doing

      yes AAAAAAAAAAAAAAAAAAAAAA | nc -v -v -l -p 2222 > /dev/null

on one side and then hitting it with

      yes BBBBBBBBBBBBBBBBBBBBBB | nc othermachine 2222 > /dev/null

from another host will saturate your wires with A's and B's."

Of course to get to 10Gbps throughput you may need multiple source and destination systems.


Hope this helps.
