Hi List,
maybe you have a clue about the issues im having since several months.
My Homeserver is running Debian Jessy right now, the network issues
where there with wheezy aswell.
after a fresh boot my network behaves like it should archiving near gbit

I don't recall but it is likely that in order to use the vhost-net
driver that the newer kvm and related packages are required.

Have you loaded the vhost-net kernel module? It is a huge lever for
network performance.

If I do cat /dev/zero | nc -u -p 1666 doris.namkas 1666
