Are you running the iperf server or client on the r8169?
I'm running the iperf server on the r8169 and get the following results:
mb@homer:~$ iperf -c 192.168.2.50 -t120 -i10
------------------------------------------------------------
Client connecting to 192.168.2.50, TCP port 5001
TCP window size: 16.0 KByte (default)
------------------------------------------------------------

[ 3] 0.0-120.0 sec 9.31 GBytes 666 Mbits/sec
Looks acceptable to me.
The iperf client device is a BCM5780.
