Minecraft 18w43c, Minecraft 18w44a
-
Quad-core @3.4 Ghz 16GB RAM
ArchLinux with Linux 4.18.16 and Java 11 -Xmx8G
-
Unconfirmed
Steps to reproduce
- Run MC 18w44a Server or Client with integrated Server (happened too in 18w43c, for previous ones I don't know)
- Create a new superflat world defaults settings, set doMobSpawning to false and /kill the existing mobs. (for comparing purposes).
- Idle (in the case of a Server, let it run with no player on)
- 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%.

MC-138071 Main thread uses 100% of one CPU core when no users are logged in, busy-waiting over java.lang.Thread::yield, makes it hard to profile properly
