    Description

      Steps to reproduce

      1. Run MC 18w44a Server or Client with integrated Server (happened too in 18w43c, for previous ones I don't know)
      2. Create a new superflat world defaults settings, set doMobSpawning to false and /kill the existing mobs. (for comparing purposes).
      3. Idle (in the case of a Server, let it run with no player on)
      4. Repeat the same steps with MC 1.13.2.

      Observations

      MC 18w44a constantly runs at at least 100% of Core usage while under the same environment, MC 1.13.2 only needs 10%.
