[lxc-devel] poor 10G ethernet performance

[David Kang]

 Hello,

 My group is measuring network performance of LXC.
We can get 9 Gig/sec between the host machine and the other machine.
But, between an LXC instance and the other machine, we only get 3.7 Gig/sec.
We also measured performance between the LXC instance and its host machine.
It is 3.5 Gig/sec.
Is it normal?
Is there any way to improve the performance?

We use Linuxkernel 2.6.38.
We used bridge for networking.

 Thanks,
 David
