      We're experencing huge slownesses on the neutron API with many routed provider networks, many projects and RBAC rules to share them with projects.

       

      Here's some figures to reproduce the issues and results as admin and user:

      235 RPN, 436 subnets, 99k rbac rules, 436 projets, 3 physnets (1 per AZ).
      response times :
      admin: 31s,
      user: 29s

      It's been covered in the past through this launchpad and some fixes have been delivered:
