We have almost default se
If you can get 9Gbps with multiple connections I'm guessing it's because of
latency and the buffer size of your sockets. If you change the sending and
receiving window size you should be able to fully saturate the link with
one connection (though there are several reasons for not doing that).

Hi,
I am facing issue with performance of 10 Gigabit Ethernet.
Environment 2 hosts each:
- 2 * Intel(R) Xeon(R) CPU E5-2690 v2
- Intel 82599ES 10Gb Ethernet
- 128GB RAM
System:
- Centos 6.5 delivered by fuel 6.0
