I'm my opinion, the security-group related ones are probably the most importants, as that specific part of neutron get's a lot of calls from all L2 agents in compute nodes. In the case of backporting, I'd, at least, let some time to get those changes cured, and make sure they are not introducing any new failure mode.

Hi all,
there is a series of Neutron backports in the Juno queue that are intended to significantly improve service performance when handling security groups (one of the issues that are main pain points of current users):
- - https://review.openstack.org/130101 - - https://review.openstack.org/130098 - - https://review.openstack.org/130100 - - https://review.openstack.org/130097 - - https://review.openstack.org/130105
The first four patches are optimizing db side (controller), while the last one is to avoid fetching security group rules by OVS agent when firewall is disabled.
AFAIK we don't generally backport performance improvements unless they are very significant (though I don't see anything written in stone that says so), but knowing that those patches fix pain hotspots in Neutron, and seem rather isolated, should we consider their inclusion?
Should we come up with some "official" rule on how we handle performance enhancement backports?
