Hi,
I have several LXC containers, running on Ubuntu Lucid's current kernel,
2.6.32-22.
Network performance from the containers to the LAN is fine.
However copying files (scp/rsync/whatever) between the containers and
their host is extremely slow - a steady 32 kb/sec.
I am using bridged network
Hi,
Send
ifconfig br0from 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 0

Just FYI in case you were unaware - it seems one of your MXs is black
holed.
I tried to email you direct, but messagelabs said;

Might fix your problem, YMMV; this worked for me.

Bam! Problem fixed.
All I needed was the 'sg' option - tso wasn't enabled anyway.
Now getting a healthy 15-16 mbyte/sec.

Performance issues with networking and veth devices can be often
linked to the implementation of hardware acceleration in various
kernel drivers for various NICs. I found this from a lot of toggling
of the acceleration tunables with ethtool. I'm sure there's a deeper
issue with the drivers, but it
