I must apologize for suspecting the kernel for my problems. After some bisect attempts I finaly noticed the following:
> cat /etc/sysctl.d/net.conf > net.ipv4.tcp_window_scaling = 1 > net.core.rmem_max = 16777216 > net.ipv4.tcp_rmem = 4096 87380 16777 > net.ipv4.tcp_wmem = 4096 1638
After removing those values I finally had sane iperf values. No idea how those got there, perhaps they made sense when I first setup the box, which is some years ago..
Anyway, thanks all for your help :)
