Hmmm:

root at mankind:~# iperf -t 30 -c undertaker
------------------------------------------------------------
Client connecting to undertaker, TCP port 5001
TCP window size: 16.0 KByte (default)
------------------------------------------------------------

Seems a bit faster than 100M, but not even close to what you are getting.
