I tested multi-threads loopback netperf on our machines, no clear
regression or improvement find on our NHM-EP/NHM-EX/WSM-EP machine. 

but on our 4 sockets tigerton machine with 2048 clients, performance
increase 20% for TCP_RR subcase, and 10% for TCP_STREAM32 subcase;
and on our 2 sockets harpertown machine, the TCP_RR subcase increase
15%. 

The data is quite good! 

Don't find performance change on UDP_STREAM1 and UDP_RR1 subcase.
