Public bug reported: With upgrade of Neutron from 23.2.0 to 24.0.0.b1 there is a 2 times regression in response time for security groups listing.
Moreover, on 23.2.0 this listing could be coming from smth like cache from time to time, as API response was super low after multiple subsequent requests. This no longer happens on 24.0.0.b1. Some investigation on what caused regression led me to the patch https://review.opendev.org/c/openstack/neutron/+/883907 In test environment I was using neutron was running with eventlet inside a virtualenv. I also installed neutron manually from the specific SHAs to show the difference in execution time between 2 commits coming each after another. Log with requests is attached. ** Affects: neutron Importance: Undecided Status: New ** Attachment added: "regression_pinpint1.txt" https://bugs.launchpad.net/bugs/2081173/+attachment/5819313/+files/regression_pinpint1.txt ** Description changed: With upgrade of Neutron from 23.2.0 to 24.0.0.b1 there is a 2 times regression in response time for security groups listing.
