Hi Neutrinos! Inspired by Julia Kreger's presentation on the summit [1] I wanted to gather some ideas about the change in Neutron API performance. For that I used Rally with Neutron's usual Rally task definition [2]. I measured against an all-in-one devstack - running always in a same sized VM, keeping its local.conf the same between versions as much as possible. Neutron was configured with ml2/ovs. Measuring other backends would also be interesting, but first I wanted to keep the config the same as I was going back to earlier versions as long as possible. Without much pain I managed to collect data starting from Yoga back to Pike. You can download all Rally reports in this tarball (6 MiB): https://drive.google.com/file/d/1TjFV7UWtX_sofjw3_njL6-6ezD7IPmsj/view?usp=s... The tarball also contains data about how to reproduce these tests. It is currently available at my personal Google Drive. I will keep this around at least to the end of July. I would be happy to upload it to somewhere else better suited for long term storage. Let me also attach a single plot (I hope the mailing list configuration allows this) that shows the load_duration (actually the average of 3 runs each) for each Rally scenario by OpenStack release. Which I hope is the single picture summary of these test runs. However the Rally reports contain much more data, feel free to download and browse them. If the mailing list strips the attachment, the picture is included in the tarball too.
