Bug description:
  On containerized setups with multiple cpus and hyperthreading on the
  metals the containers can see a large number of cores. With the
  default worker multiplier settings this eg. results in 112 workers
  plus a leader processes on one of our installs. With HA we have then
  3x113 processes serving in total, which is a bit of a waste (3x16G of
  RSS for one service, as an example)

  While this can be tuned down I'd suggest to cap the number of workers
  when the worker-multiplier setting is on default to make this more
  sensible out of the box
