Hi all, In our Grizzly deployment, we found a distinct performance reduction on networking throughput.
While using hybrid vif-driver, together with ovs plugin, the throughput is dramatically reduced to 2.34 Gb/s. If we turn it back to common vif-driver, throughput is 12.7Gb/s. A bug is filed on it: https://bugs.launchpad.net/neutron/+bug/1223267 Hybrid vif-driver makes it possible to leverage iptables-based security group feature. However, this dramatical performance reduction might be a big cost, especially in 10 GE environment. It'll be appricated, if you share some suggestions on how to solve this issue. Thanks very much. Best, Robin Wang
