      We observed higher CPU utilization of this pod during an extended steady workload test compared to 4.11.6 with the same test.

      Our environment is a SNO node with the vRAN DU profile applied.
      The test consists of running a steady workload pods and then monitoring the min/max/avg CPU for all management pods during an 8 hour run.

      Measurements are in milli-cpus
