      1. Create all objects at once, 20 UDNs on 24 nodes, a few pods -> start up time for UDN controllers
      2. Startup time is unreasonable
      3. Locking of informers takes time
      4. 20 NAD controllers reconciliation locking is taking time
      5. Initial addition of resources is taking time
      6. Startup time is unreasonable

      All the controllers are hogging the informer lock
