Hello!

I am getting very poor networking performance under OpenVZ. My setup looks like this:

|pfsense|
XXXX|XXXX
VLAN1 | VLAN2
SRV1 | SRV2

For pfsense, I am using three virtio network adapters:

net0: virtio bridge=vmbr0
net1: virtio bridge=vmbr1
net2: virtio bridge=vmbr1

On the container, I am using:
Network Device (VETH0)
BRIDGE: VMBR1
VLAN TAG:1
No firewall

The operating system is the last debian min.

Whenever I download a file (apt-get upgrade, etc) I download at a MAX of 20KBps. One thing to note, on the server that is not behind pfsense I download at over 10MBps. This server is using venet, not veth. I can't seem to trace down whether it is related to pfsense, or a configuration issue with openvz.

I have two hardware nodes that experience the same issue. Max of 20KBps. I am getting a feeling that this is related more to pfsense then proxmox/openvz. I will continue testing this tomorrow.

Any suggestions are welcome in the meantime :)

Try in pfSense: "Disable hardware checksum offload" (System -> Advanced -> Networking) and reboot pfSense. I had the same performance issue (and download FROM INSIDE pfSense was fine).
