Hi,
I recently ran into a network performance issue on my n3700 machine with 4 RTL8111 nic.
Even on a clean pve host system, I installed iperf3 via apt-get and performed speed test, the result is not right.
In that case, I could get about 940Mbps from my laptop to PVE host, but only 890Mbps from PVE host to my laptop. It got even worse inside vms with virtio nic.

Is somebody can help figure it out?
