We observed a high cpu utilization in our environment(about 15 HVs) when doing a high rate of port insertion/deletion. It seems ovn-northd recompute everything on NB change, do you have any optimization suggestion on this scenario? > CPU is rather busy on HVs, but there is an ongoing optimization with very > promising test result: > https://mail.openvswitch.org/pipermail/ovs-dev/2018-April/346136.html Is there will be a similar incremental processing for ovn-northd in your roadmap?
