iperf indicates that the network throughput is about 930MB though:

root@zaxen01:[~]$ iperf -s
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
------------------------------------------------------------
[  4] local 196.34.x.x port 5001 connected with 196.34.x.x port 45453

[  4]  0.0-10.0 sec  1.09 GBytes    935 Mbits/sec

29.1MB/s (megabytes) is 232.8 megabit. Yes, you still have room forimprovement in that regard. You said sata drives, but what spec.? Anyidea on your throughput for your source/destinatation hard drives?Would they both sustain higher than 29.9MB/s ?
