[Lxc-users] Dreadful network performance, only to host from container

[atp]

Hi,

Send 

ifconfig br0    from the host
ifconfig eth0   from the container

and the version of lxc you're using. Do you have anything special with 
the /etc/sysctl.conf? 

On a completely blank container with no tuning, I get with scp;

host->container   squashfs.img     100%  639MB  33.6MB/s   00:19    
container->host   squashfs.img      100%  639MB  29.0MB/s   00:22    

Both tests inside the container. The limiting resource here is cpu for
the
encryption. 

I'm on kernel 2.6.34/fc12 for this.
