Sorry. I was not receiving updates on this bug. As it can be seen in the last tests I did in comment 6, the download and upload speed were good between an instance and the Internet, not only between two instances running on separate compute nodes.
Also, the physical interface used by br-ex on my network node has GRO turned ON and this doesn't seem to affect the network performance, so I'm not sure that's the issue: root@quantum-network:~# ovs-vsctl list-ports br-ex eth0 qg-bb60f501-45 root@quantum-network:~# ethtool -k eth0 Offload parameters for eth0: rx-checksumming: on tx-checksumming: on scatter-gather: on tcp-segmentation-offload: on udp-fragmentation-offload: off generic-segmentation-offload: on generic-receive-offload: on large-receive-offload: off rx-vlan-offload: on tx-vlan-offload: on ntuple-filters: off receive-hashing: on -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1252900 Title: Directional network performance issues with Neutron + OpenvSwitch To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/1252900/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
