Package: linux-image-3.2.0-4-amd64
Version: 3.2.51-1
Hi,
We have two machines which we want to use as an LXC host. The hardware and
software setup for both machines is identical. After a fresh install of Debian
Wheezy we discovered that we had poor network perfomance (compared to Debian
Squeeze). We've tried several workarounds to get the old network performance
back, but weren't successful. After using the kernel from wheezy-backports we
gained back (some of) the network performance we had with Debian Squeeze.
We've used iperf to get some idea of network throughput.
