If this article is true, one wouldn't need usb 3.0 for gigabit ethernet anyway...

*shrug* The article is pretty old and technology has moved on quite a bit but the numbers in the main article are still pretty suspect. The window size it is using is tiny and its not going to give you good performance with that. One of the comments from the author has results from using different buffer sizes and its still not good performance.

Using iperf I get the following results:

Code:
------------------------------------------------------------
Client connecting to storage, TCP port 5001
TCP window size: 16.0 KByte (default)
------------------------------------------------------------
[  3] local 192.168.1.50 port 53305 connected with 192.168.1.20 port 5001
[ ID] Interval       Transfer     Bandwidth
[  3]  0.0-10.0 sec  1.03 GBytes   887 Mbits/sec

That is from a single core HT P4 to an dual core Opteron over GigE. The P4 is one of the original Northwoods so thats around 2003 and the Opteron is a Santa Ana which is around 2006.
