There is, iperf. Run iperf -s on one end, and iperf -c on the other, thus:-

alan at wopr64:~$ iperf -s
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)

revo at revo:~$ iperf -c
Client connecting to, TCP port 5001
TCP window size: 16.0 KByte (default)
[  3] local port 47945 connected with port 5001
[ ID] Interval       Transfer     Bandwidth
[  3]  0.0-10.0 sec  67.4 MBytes  56.5 Mbits/sec
