Hi, There are quite a few and I'd like to offer some explanations: Nova: https://review.openstack.org/#/c/16617/, https://review.openstack.org/#/c/16618/ and https://review.openstack.org/#/c/16619/ are all patches to improve performance when nova uses Quantum. By mistake yesterday I cherry-picked the last one and it caused a mess. I have abandoned that change. Quantum: https://review.openstack.org/#/c/16386/ - this imporves performance with the database when quotas are enabled. Mark and Alan raised some very good and relevant concerns. These have been addressed by https://review.openstack.org/#/c/16609/. If you guys feel that these are too risky at the moment then we can wait a few days. https://review.openstack.org/#/c/16223/ - patch enables linuxbridge plugin to be optimized. This requires a patch in Nova. The code is "backward" compatible - it does not break with the current version and with the version that will have Nova create the bridge. I have updated the commit message which will hopefully be a lot clearer now. https://review.openstack.org/#/c/16610/ - updates the clear_db - this helps save memory with the unit tests. https://review.openstack.org/#/c/16615/ - bug fix for interface mappings (had to do a little tweak here due to the fact that code was re-factored. rkukura has given it his thumbs up) https://review.openstack.org/#/c/16616/ - fix for floating IP allocations Sorry for the messed up mail, but I felt I owe a few explanations. Thanks (I am feeling like farmer brown at the moment) Gary
