Hi Serge,<div><br></div><div><div>Sorry for my late answer. I do use veth, but the other experiments also use it. But my guess there is might be some kind of kernel customization, so they can reach these speeds, but unfortunatelly I am not aware of what customization they made on their kernels.</div>
<div>A little more about my setup... My kernel's version is: 3.20.0-23-generica-pae.</div><div>And the network setup of my containers:</div><div>lxc.network.type=veth</div><div>lxc.network.link=lxcbr0</div><div>lxc.network.flags=up</div>

</div></div>There shouldn't be a difference between lxc and network namespaces...<br>
When you say you reach 1Gbps with network namespaces, how are those<br>
set up? Are they using veth? How about your lxc setup?<br>
