Hi, good that you're looking at this, You could create a lot of ports with this method [1] and a bit of extra bash, without the extra expense of instance RAM. [1] http://www.ajo.es/post/89207996034/creating-a-network-interface-to-tenant-network-in This effort is going to be still more

Re: [openstack-dev] [Neutron] OVS flow modification performance

Thanks for doing this. A couple of questions: What were your rootwrap settings when running these tests? Did you just have it calling sudo directly? Also, you mention that this is only ~10% of the time spent during flow reconfiguration. What other areas are eating up so much time? Cheers, Kevin

I'm sending out this mail to share the finding and discuss how to improve with those interested in neutron ovs performance. TL;DR: The native of_interface code, which has been merged recently and isn't default, seems to consume less CPU time but gives a mixed result. I'm looking into this for
