Hello Mark:

The first thing I would propose you is to switch from hybrid plug to native. That will improve the performance avoiding the veth pair to a Linux Bridge to plug the TAP port there. With native plug type you'll connect the TAP device directly to the OVS br-int. It could be possible that the packet lost is happening in the Linux Bridge.

In order to change this, you should swap from "firewall_driver=iptables_hybrid" to "firewall_driver=openvswitch" or None. Then you'll need to restart the agent and re-plug the VMs (stop or migrate them).

That will, for sure, improve the performance and will make shorter the datapath. Now OVS will be the only backend levering the data packets.

Regards.
