 Sorry, forgot to mention that I am trying to connect to the vlan ports.
vmbr1, which doesn't use OVS, is fast as expected.

I hope that we have a communication Problem here and I didn't miss
something really basic about OVS and wasted everyones time.
box-b doesn't use OVS yet. box-b uses normal linux bridging on a untagged
VLAN Port (VLAN ID 1115) on a switch. box-a connects to two LACP bond'ed
Ports on that some switch that have multiple tagged VLAN IDs, one of them
being 1115.

[root at box-b /root $ ovs-vsctl show
872e809c-3121-4a4f-9fe8-8e436a7cf101
    ovs_version: "2.3.1"
########

Any Ideas where I could look at?
